On bad args, show usage and exit
The lsrc(1), mkrc(1), rcup(1), and rcdn(1) commands will now print a
usage message and exit immediately (with 64, `EX_USAGE`) when given an
option it does not understand.
This includes `--version` and `--help`.
Normal `-h` will print usage and exit successfully, as normal.
Closes #59.
