perf tools: Allow using PERF_RECORD_MMAP2 to synthesize the kernel modules maps
Allow using PERF_RECORD_MMAP2 to synthesize the kernel modules maps so
that we can use PERF_RECORD_MMAP2 to encode the kernel modules build ids
in the following csets.
It's enabled by a new symbol_conf.buildid_mmap2 bool field, which will
be switchable in following changes.
