perf tools: Store build id when available in PERF_RECORD_MMAP2 metadata events
When processing a PERF_RECORD_MMAP2 metadata event, check on the build id misc bit: PERF_RECORD_MISC_MMAP_BUILD_ID and if it is set, store the build id in mmap's dso object. Also adding the build id data to struct perf_record_mmap2 event definition.
