[Intel-gfx] [PATCH i-g-t 8/8] lib: add a command line option to enable debug output in tests

[Gore, Tim]

See my comment on patch 6.  --debug returns 'd' from getopt, which can conflict
with the short options for some tests, such as gem_render_copy and gem_seqn0_wrap.
This problem also exists for the --run-subtest.
