dev-java/protobuf-java: add 3.21.9-r1

Bug: https://bugs.gentoo.org/878467

Didn’t suppress previous revision because already stabilized on x86.

Restores features available in other bindings:
- parent version in SRC_URI to avoid the download of two tar.gz
  archives instead of one,
- patch system more valuable for users,
- parent's _SUB_slot value for consistency with main library.

Does not restore variable for MAVEN_ID, burden of maintenance it
requires manual updating.
Does not restore live ("9999") version, kept in dedicated ebuild.
