Inside `nix-shell`, `TMPDIR` (used by `mktemp`) is set to
`/run/user/<uid>` which is usually a tmpfs stored in RAM.
When fetching a large dotnet deps tree to this tmpdir from a
nix-shell (e.g. via `btcpayserver/update.sh`), this can easily exceed
system RAM and `fetch-deps` fails.
mktemp arg `-t` is deprecated and can be omitted.
The source used to download a particular package still isn't
deterministic in nuget. Even worse, the hash of the package can vary
between sources. This makes nuget use the first enabled source
containing the package.
The order of the dependencies may be slightly different because it now
uses glob order of the lower-case package names and versions, instead of
sorting the output.
If the package actually downloaded was the first source that contains
the package, then it will be hashed from disk to avoid downloading it
again.
Previously we had an assert that would complain when nugetDeps wasnt set,
which also didnt allow any passthru attributes (like fetch-deps) to be
build. That causes a cycle where you need nugetDeps to fetch the nuget
deps, but arent able to build the script to do so.
For example, this script doesn't work for `xivlauncher` because its
proper `pname` is `XIVLauncher`, and `mktemp` complains about "too few
X's":
$ mktemp -td "XXXXXX-XIVLauncher-home"
mktemp: too few X's in template ‘XXXXXX-XIVLauncher-home’
vs
$ mktemp -td "XIVLauncher-home-XXXXXX"
/tmp/XIVLauncher-home-EdGMei
This makes buildDotnetModule restore nuget dependencies for the
platforms set in meta.platforms. This should help with generating
lockfiles for platforms other than the host machine.

cp on macOS doesn't support the -T flag, which causes the fetch-deps
script to fail. Use Nix's coreutils to ensure the script works
consistently across all platforms.

same functionality.
Some packages are defined by the build proccess, and change every time
the dotnet-sdk package changes. To avoid having to regenerate every
dependant packages dependencies every dotnet update, this moves these
packages into the `dotnet-sdk` `passthru` attribute, and includes them
every time `buildDotnetModule` is used.
The --self-contained and --no-self-contained switches were
added to the dotnet build command starting with .NET 6.
The switch is equivalent to the setting the SelfContained
property, so we use the property for backwards compatibility.
In some cases `$pkgs_src` can be a path. For example with `FSharp.Core` when it comes with dotnet SDK.
In these cases we need to fallback on default URL otherwise curl fails.
Sometimes I want to pass a different implementation of `mkNugetDeps`.
For example in private repos, it can be handy to use `__noChroot = true`
and bypass the deps.nix generation altogether. Or some Nuget packages
ship with ELF binaries that need to be patched, and that's best done as
soon as possible.
