[Piglit] [PATCH v2 3/5] util: Add a -list-subtests option that will list all the subtests

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

The utility is that all.tests can do 'sometest -list-subtests' to
automatically get the list of subtests to run.  Since the syntax for
selecting subtests is regularized, this works quite well.
