libxbps: separate virtualpkg conf stuff from repository_pool_find_pkg.

Browse Source 
Now to find a virtualpkg set by the user in conf file, there is a new
function: xbps_repository_pool_find_virtualpkg(). Use it in some
places to make jpeg -> libjpeg-turbo (and other pkgs that can be
replaced with other virtual pkgs) work correctly even if installed
multiple times.
