policycoreutils: fixfiles: usage errors are fatal

The idea is to print a usage error, then terminate with EXIT_FAILURE.

Don't print the usage error twice when run with no command.

Don't try to check for bogus extra arguments _after_
performing a long-running operation... particularly
if that operation terminates the script with EXIT_SUCCESS first.
