podfix: class to remove Pod::Man versions from manpages
Manpages generated by Pod::Man contain the version number, which isn't
reproducible if we're using the host Perl to generate manpage.
One option is to always depend on perl-native when generating manpages
but this is a heavy dependency, so instead strip out the versions in
do_install().
