[Intel-gfx] [PATCH i-g-t] tests/igt_command_line.sh: Allow testing individual tests

[Daniel Vetter]

meso will use this to run the tests for all testcases in parallel, for
great speedup!

v2: Fix bugs in the conversion. Oops, I broke the automake build.

v3: Try harder at being posix shell compliant.
