[Buildroot] [PATCH] apply-patches.sh: use everything from the series file

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

When a series file exists, we should use every file mentioned in it,
not just the ones ending with .patch or .diff. Also, there's no need
to uncompress anything if it's mentioned in a series file (the tools
that manipulate series files don't support compressed patches).
