Test: Make create_compress_files.c a little more flexible.

Browse source 
If a command line argument is given, then only the test file
of that type is created. It's quite dumb in sense that unknown
names don't give an error but it's good enough here.

Also use EXIT_FAILURE instead of 1 as exit status for errors.
