llvm.org.eclass: Do not require separate manpage dist for every PV

Do not require a separate manpage dist for every minor release.
Instead, use the 16.0.4 tarball for 16.x releases going forward.
This makes sense since manpages rarely change -- at least for all
the 16.x releases, all that's been changing were the build date
and the version number in extraclangtools manpage.
