perf inject: Clarify build-id options a little bit

Browse Source 
Update the documentation of --build-id and --buildid-all options to
clarify the difference between them.  The former requires full sample
processing to find which DSOs are actually used.  While the latter simply
injects every DSO's build-id from MMAP{,2} records, skipping SAMPLEs.
