perf machine: Set PROT_EXEC for executable PERF_RECORD_MMAP records

Browse source

The kernel doesn't fill the map 'prot' field for PERF_RECORD_MMAP
records, and we will use that info to replace checking for
MAP__VARIABLE, so store that when processing the
PERF_RECORD_MISC_MMAP_DATA perf_event_attr.header.misc bit.
