Manually check xdelta exit codes.

This is needed because 'xdelta delta' returns 1 even when the delta
creation succeeds. This was causing makepkg to exit after the command
due to bash's -e option.

Some information from the xdelta man page:
The delta command exits with status 0 to indicate that no differences
were found, with status 1 to indicate that some differences were found,
and with status 2 to indicate an error of some kind.
