[Piglit] [PATCH] RFC: README.md: update test sets documentation

[Alejandro Piñeiro]

Since commit "tests: use meta profiles"
(400dcd5cf18ac51ab8e9681d8ecab4132986efbd) some test sets are not
represented anymore as python scripts. So first, it would be good to
mention it, and second it would be good to mention that it would be
better to run the test sets using the set name, not directly the
python script.

RFC because I have been struggling with the wording.

Basically I was not understanding why ./piglit run tests/all.py was
not working, and the README.md didn't help me. So somehow it needs to
be tweaked, but not sure how. Current patch tries to be as small as
possible, but perhaps it is too small.
