perf lock: Add percpu-rwsem for type filter

percpu-rwsem was missing in man page. And for backward compatibility,
replace `pcpu-sem` with `percpu-rwsem` before parsing lock name.
Tested `./perf lock con -ab -Y pcpu-sem` and `./perf lock con -ab -Y
percpu-rwsem`

 	Show lock contention only for given lock types (comma separated list).
 	Available values are:
 	  semaphore, spinlock, rwlock, rwlock:R, rwlock:W, rwsem, rwsem:R, rwsem:W,

 	Note that RW-variant of locks have :R and :W suffix.  Names without the
 	suffix are shortcuts for the both variants.  Ex) rwsem = rwsem:R + rwsem:W.
