`$OBJCOPY` is not available in bootstrap tools

Add this hook to checkPhase to allow for running MPI application in
the sandbox. It detects the MPI implementations and sets the respective
environment variables.
Previously `writeDarwinBundle` used a handcrafted shell wrapper, however
this causes issues on Apple Silicon Macs as script-only application
bundles are always run under Rosetta[0][1].
Replacing the handcrafted shell wrapper with a binary wrapper allows
apps to run natively instead of requiring Rosetta. However, this means
we can no longer use `$1` and `$@`.
After checking nearly every current usage of `desktopToDarwinBundle`,
there were no apps that used `%[fFuU]` before the last argument, meaning
removing them naively is good enough for the current apps.

Before the change the hook had a chance to run `strip` against the same
file using multiple link paths. In case of `gcc` `libgcc.a` was stripped
multiple times in parallel and produces corrupted archive.
The change runs inputs via `realpath | uniq` to make sure we don't
attempt to strip the same files multiple times.
This change adds a flag to update shebang paths that point to the Nix
store. This is particularly useful when a cross-compiled package uses
same script at compile-time and run-time, but the interpreter must be
changed since hostPlatform != buildPlatform.
When `--add-flags` is not used, `flagsBefore` is unset. This causes an error when invoking `makeWrapper` from a context that sets `-o nounset`, as is done in `buildDotnetModule`.
This change makes `makeWrapper` safe for use in these conditions.
If multiple files with the same build id were found, we silently randomly
overwrote one with the other.
Change the order to make the output deterministic, and emit a
warning when overwriting.
When I authored the nix file in
335a9083b0,
`makeSetupHook` didn't know about `passthru` or `meta`.
So I foisted these attributes on the
derivation with `.overrideAttrs`.
Commits ba895a7da8 and
48034046bf enabled
`makeSetupHook` to receive these attributes directly.
It seems advisable to use that instead of `.overrideAttrs`.
AFAIK this doesn't have a noticable effect for typical
Linux executables, but will avoid setting the timestamp
inside the file for Windows executables to the build
date.
This fixes multiple entries being returned from getDesktopParam, e.g. in the
case of localized key names: 'Name', 'Name[de]', and makes this function to
match this key exactly instead of a pattern for the same reason.
Currently, separate-debug-info adds a debug output, and the build fail when it is
not created. the output is only created when at least one elf file is
stripped.
As a result, adding separateDebugInfo = true on a lib will break the
static build (unless the lib also contains an executable). In order to
not have to remember to add an exception every time, let's just create
the debug output unconditionally.
