perf stat: Enhance option parse error message
Print related option help messages only when it failed to process
options. While at it, modify parse_options_usage() to skip usage part
so that it can be used for showing multiple option help messages
naturally like below:
$ perf stat -Bx, ls
-B option not supported with -x
usage: perf stat [<options>] [<command>]
-B, --big-num print large numbers with thousands' separators
-x, --field-separator <separator>
print counts with custom separator
