[PATCH perf/core 1/8] [BUGFIX] perf probe: Make --funcs option exclusive

--funcs option is a command which should be given exclusively.
This adds PARSE_OPT_EXCUSIVE flag on --funcs (-F) option.

Without this, 'perf probe --funcs -l' just shows the list of
probes. With this, it shows error message correctly.

This also fixes the help message and the documentation.
