tests: Separate tests with lots of subtests

Currently, when trying to run i-g-t tests with piglit, it takes up
to 20s until the first test is executed.
The main reason is that gem_concurrent_all has ~500k subtests,
overkilling piglit.

This patch separates gem_concurrent_* tests from the rest of the tests,
creating two files test-list.txt and test-list-full.txt.
The piglit can now enumerate the i-g-t tests within a decent few seconds.
The second list could be used when trying to execute specific these tests.

v2: Rebased
