lang/go*: Update to Go 1.22 snapshot

- Add overridable BUILD_DEPENDS on shells/bash, but only for Go 1.22+
- Since lang/go121 also depends on it, allow SHEBANG_FILES to be
  overridden
- Re-roll the patch
- Update lang/go120 to co-exist with lang/go-devel update
- Update lang/go121 to co-exist with lang/go-devel update
