pkgdelta: Use high compression options offered by xdelta3
* Add -9 which is the highest compression level.
* Use lzma for secondary compression.
Decompression speed is largely unaffected as most cycles are consumed
by xz for re-compression.
Some numbers:
clang x86_64 [3.5.0-2.1 to 3.5.0-3]
17.21MiB default (0.73)
15.67MiB -9 (0.67)
13.59MiB -9 -S djw (0.58)
12.01MiB -9 -S lzma (0.51)
inkscape x86_64 [0.48.5-3 to 0.48.5-4]
02.69MiB default (0.21)
01.64MiB -9 (0.13)
01.30MiB -9 -S djw (0.10)
01.01MiB -9 -S lzma (0.08)
