Subject: add support for HOOKDIR/INSTDIR as arrays

This is a really ugly patch, but allows mkinitcpio to read hooks from
multiple locations, namely:

  /usr/lib/initcpio/{install,hooks}
  /lib/initcpio/{install,hooks}

Preference is given to the first, and all files included with mkinitcpio
are moved there.
