igt_command_line.sh: Actually check things during distcheck

This script is invoked in several different ways and the directories
to use vary depending on the invocation. The handling of test-list.txt
has been working before, but executing the individual command line
handling tests have just skipped everything except shell scripts. Now
"make distcheck" checks everything "make check" does, as does
executing the script by hand.
