Fix several issues with xdelta

1) The changes to sync.c look big but there are mostly caused by
the indentation. Fix a bug where download_size == 0 because the packages and
deltas are already in the cache, but we still need to build the deltas list
and apply the deltas to create the final package.

2) Fix the gzip / md5sum issue by switching to xdelta3, disabling external
recompression and using gzip -n in pacman, and disable bsdtar compression
and using gzip -n in makepkg.
