community/dotnet7: enable ppc64le
Enables ppc64le.
Branch off of !41749 (merged):
A bug surfaced in dotnet7 that causes issues with parallel restore operations when using mono-flavored runtime. This is likely caused by EAGAIN errno bleeding from another thread, but upstream is still investigating. A workaround was implemented via a patch that ignores EAGAIN errors, which unblocks proper s390x and ppc64le support.
See https://github.com/dotnet/runtime/issues/77364
Other changes:
- patch clean-up and updates
- added runtime fixes for ppc64le
- all binlogs are now able to be scooped by pipelines
- fixes s390x build with clang-15 now forcing
