Notices: no RPCS3 wording in parts a release ships

The SDK's LLVM entry pointed to an RPCS3 entry no release carries, and the
core-info entry named rpcs3_libretro.info and tooling/rpcs3, neither of which
is in the repository or the package any more.

Verified: TMPDIR=$PWD/build/tmp bash tools/verify.sh -> verify: PASS
(format unit build integration evidence).
