Add a mkinitcpio pacman script

This script runs on mkinitcpio package updates as well as on kernel updates that
have the pkgbase file on their modules directory. It will use the contents of that
file to determine which preset to run or, in case not pkgbase file is passed to it,
it will run all presets with -P.
