ftrace: Have set_ftrace_pid use the bitmap like events do

Browse Source 
Convert set_ftrace_pid to use the bitmap like set_event_pid does. This
allows for instances to use the pid filtering as well, and will allow for
function-fork option to set if the children of a traced function should be
traced or not.
