[3.17] community/dotnet7: enable s390x

dotnet7 was initially targeted for 3.17 release on x86_64, armv7, aarch64 and s390x. Due to a last minute bug that made build unstable, s390x was not released. Since then, a workaround for this bug was found, and was implemented in edge.

To match the supported platforms for dotnet6, dotnet7 should also support s390x.

This MR thus backports that workaround.

Other changes:

• Patch to fix rebuilding with dotnet7-build
• Updated Patch-Source on patches
• Better binlog scraping in pipelines
• Updated patches for mono

Note: pkgrel was not bumped as to only build this on s390x as changes to other platforms is cosmetic or build infra-related.
