perf help: Fix --help for builtins
It seems that commit cc5848213329 ("perf help: Remove use of die and handle errors") caused the problem - it changed the initial value of 'help_format' from HELP_FORMAT_MAN to HELP_FORMAT_NONE. This broke the --help option for all builtins, that would produce no output, while 'man perf-top' would work it MANPATH is properly setup.
