[igt-dev] [PATCH i-g-t v4 5/6] scripts/test_list.py: speedup testlist check logic

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

Now that the build system will generate the testlist for us,
just read them when checking for missing symbols.

This should speed up a log the check logic.

After the change, touching on a single file and rebuilding the
testplan with check enabled is a lot faster:

	$ touch tests/xe/xe_compute.c
	$ time make
	ninja -C build
	ninja: Entering directory `build'
	[10/10] Generating docs/testplan/i915_tests.html with a custom command

	real	0m4.510s
	user	0m5.944s
	sys	0m0.217s

This can be improved even further if we split the test_executables
dependencies per driver.
