Remove package name dependency from libalpm

Previously, package names must match a specified scheme or they will cause
pacman add operations to fail. This is not a very intelligent or necessary
way to act, so remove the dependency on the name of the package to be
installed and read all relevant information from the metadata instead.

This does have one causality to be addressed later- pacman cache cleaning
functionality, which has never been phenomenal, just lost most capability.
