UPSTREAM: Sort cipher_files, to make build system generation more deterministic

This applies the upstream patch to util/import_gcry.py in bzr commit
4572 (http://bzr.savannah.gnu.org/lh/grub/trunk/grub/revision/4572),
which makes the generated build system files independent of the
(system-dependent) order of files in os.listdir.  Applying this patch
and re-running autogen.sh eliminates a huge amount of noise in
subsequent commits.

BUG=chromium:265918
TEST=With the complete patch series, built a complete x86-generic image,
     and booted it via UEFI on both 32-bit and 64-bit UEFI platforms.
