If opening argv[1] + ".txt" fails, try opening argv[1] without suffix

Previously, running "showrgb /usr/share/X11/rgb.txt" would give the
confusing error message:
 showrgb:  unable to open rgb database "/usr/share/X11/rgb.txt"
since it was really looking for rgb.txt.txt.

Now it just works, allowing users to use filename completion.
