Find package dependencies fix for pacman.

Since the pactree utility only accepts one package name, we must iterate
through the packages rather than specify them all on the command line.
To avoid errors when febootstrap is run on a system with outdated packages,
use ls and awk on the febootstrap package cache directory rather than using
the host's outdated pacman database.
