[PATCH] xz: Add ptest support

["Xu, Chi" <chi.xu@windriver.com>]

There are two types of cases: executables and POSIX shell scripts.
The output of them are different, so run them with different method
in run-ptest.
74 test cases in all and all test cases PASS.
Add xz-ptest to PTESTS_FAST because test duration is 19s on qemux86-64.

Test results on qemux86-64:
root@qemux86-64:~# ptest-runner xz

PASS: test_lzma_vli_encode
PASS: test_lzma_vli_decode

=== END ===
PASS: test_files.sh
PASS: test_scripts.sh
PASS: test_compress.sh
DURATION: 19
