Without this change, building hplipWithPlugin on aarch64 fails with:
cp: cannot stat 'lj-aarch64.so': No such file or directory
builder for '/nix/store/p0x02ppv0n1xj46wvik3p3cn4jikmr1q-hplip-3.20.11.drv' failed with exit code 1
This is because the corresponding file in the archive is actually called
lj-arm64.so.
hplipPlatforms exists to convert between the different names; this
commit only changes the value to a correct one.
HPLIP's getSystemPPDs() function relies on searching for PPDs below common FHS
paths. None of these exist on NixOS, but the code assumes that at least one of
the directories will be found, and crashes when it doesn't (cups_ppd_path is
None and the code passes that to os.path.join).
A usable PPD search path for the running system on NixOS is
/var/lib/cups/path/share, so this patches the source to check this path as well.
This should fix the NixOS case and keep non-NixOS cases working too.
Otherwise, things like hp-setup segfault if you run them from another
nixpkgs checkout:

Beginning with commit 8ffd6af27e,
the build recipe for `hplipWithPlugin` explicitely drops a
udev rule file that is delivered with the sources.
In `hplip` (without plugin), the rule file is retained.
The udev rules takes care of uploading firmware
to certain printers (and maybe of other things),
e.g. to HP LaserJet 1000.
This commit reinstates the rule file and
expands the fixup script so that the rules
are also patched in the WithPlugin version.
hplip's udev rule uses `nohup` to attempt to detach
its printer configuration script from the udev process.
However, this attempt is futile as udev
tracks its child processes with cgroups:
https://unix.stackexchange.com/a/243648
The hardcoded path to `nohup` was patched to use Nix' `nohup`.
This commit alters the patch script so
that it simply drops the call to `nohup`.
Also fixes multiples issues:
- broken plugins:
- `fax_marvell.so file is not present or symbolic link is missing`
- `lj.so library file doesn't have user/group execute permission.`
- `bb_escl.so file is not present or symbolic link is missing`
- multiple error during configuration phase which prevented `*.ppd`
generation:
- `ppdc: Unable to find include file "<font.defs>"`
- patched configure time `perl` script
- patched use of `file`
- some potentially problematic filter and services:
- patched reference to ghost script and fonts dir in filter.
- patched usb configuration service.
- patch scripts so that they refer to valid location.
Add some options:
- `withStaticPPDInstall`: Install `*.ppd` files along with `*.drv`.
When true, configure outputs: `checking for cups ppd install... yes`.
We cannot rely on wrapPythonPrograms to wrap the installed executables because
they are symlinks (which it ignores). Instead, we have to emulate it to make
the wrappers ourselves.
