[igt-dev] [PATCH i-g-t 5/7] scripts/test_list.py: better handle list of tests

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Not all test lists are regular expressions. Some are just
names. That's the case of IGT runner testlist files.

Add support for that.

In practice, this change will produce the same testlists
as before, but using a logic closer to what igt_runner()
does.
