This adds support for running XTS from piglit.
This patch was original written by Eric Anholt, but I've cleaned it up
and reworked parts of it for upstreaming, and as a result I've attached
my name as the author so ``git bisect'' and ``git blame'' will send
angry mail my way instead of Eric's.
v2: - Don't break dmesg reporting
- Use str.format consistently
- populate profile after check for xtest symlink
v3: - rebase against master
- fix spelling errors
