xbps-src: added code to verify required pkg rundeps.

Every pkg containing shared libs must register them in
common/mapping_shlib_binpkg.txt, this is where the code looks
for transforming required libs to required binpkgs.

The code will also report if a required rundep is missing from
pkg run_depends array and will suggest to add some lines to
the package template.
