markup_oops.pl: minor fixes
1. Fix a little format issue.
2. Check the return of "Getopt::Long::GetOptions". Output usage and
exit if it get error.
3. Change $ARGV[$#ARGV] to $ARGV[0].
4. Change the code which get $modulefile from modinfo. Replace the
pipeline with `modinfo -F filename $module`.
4. Change usage from "Specify the module directory name" to "Specify the
module filename".
