perf tools: Allow using PERF_RECORD_MMAP2 to synthesize the kernel map

Allow using PERF_RECORD_MMAP2 to synthesize the kernel map so that we
can use PERF_RECORD_MMAP2 to encode the kernel build id in the following
csets.

It's enabled by a new symbol_conf.buildid_mmap2 bool field, which will
be switchable in following changes.
