xdelta : only handle gz compression specifically
There is apparently no need to handle the re-compression manually when
applying a xdelta patch in case of bzip2 or xz.
Only gzip needs to be handled specifically for disabling timestamp with the
-n option.
After this patch, if xdelta is enhanced with xz support (1-line patch), it
will be transparent from pacman side.
