Subject: [PATCH] cpupower: Fix segfault due to incorrect getopt_long arugments

If a user calls 'cpupower set --perf-bias 15', the process will end with
a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi
call.  This is because the getopt_long structure currently has all of
the options as having an optional_argument when they really have a
required argument.  We change the structure to use required_argument to
match the short options and it resolves the issue.

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1000439
