Speed up test archive compression

16 times faster setting at cost of 50% larger archive.

Before:

$ time ( cat tests.tar | xz -9e > tests.9e.tar.xz )

real    0m41.640s
user    0m41.009s
sys     0m0.602s

$ wc -c tests.9e.tar.xz
913432 tests.9e.tar.xz

After:

$ time ( cat tests.tar | xz -3 > tests.3.tar.xz )

real    0m2.422s
user    0m2.294s
sys     0m0.161s

$ wc -c tests.3.tar.xz
1556080 tests.3.tar.xz
