Install Perl files to Perl vendor directory

On Fedora, the original code placed files into /usr/lib64/perl5/5.36/.
That location is not recognized by Fedora perl.

It also supresses installation and uninstallaion of packlist and perlocal
inventory files. They cannot be reliably uninstalled without
corrupting them.
