perf python: Add PERF_RECORD_{LOST,READ,SAMPLE} routine tables

So those friggin "spurious" PERF_RECORD_MMAP events were actually a
brain fart copy'n'paste error in the python binding, doh. I.e. they
weren't MMAPs, just SAMPLEs.

Fix it by providing routines for these events instead of using the MMAP
ones.
