Try dotnet/java-interop#1046

Context: dotnet/java-interop#1046

The assumption is that This Cannot Possibly Impact™ Android.
So… Does It Build™?

…no, it does not build, because dotnet/java-interop#1046 removes
the `net472` build of `jnimarshalmethod-gen.exe`, which causes
packaging to fail.  Noice.

Given that `jnimarshalmethod-gen.exe` only "worked" in Classic,
and that main is (slowly) dropping support for Classic (618bd4a),
update the repo to stop packaging `jnimarshalmethod-gen.*` and
`Java.Runtime.Environment.*`.  This should fix the packaging errors.
