Support -Sl

Adds (mostly) complete -Sl support. While pacman will also print the
version number for the package, packages.gz does not give version
numbers. Using -Si to fetch all that data would also be unthinkable.

Instead of just missing out the version number yay will print
"unknown-version". This is so that tools that expect a version number do
not break.
