perf record: Make sure to update build-ID cache

Browse source

Recent change on enabling --buildid-mmap by default brought an issue
with build-id handling.  With build-ID in MMAP2 records, we don't need
to save the build-ID table in the header of a perf data file.

But the actual file contents still need to be cached in the debug
directory for annotation etc.  Split the build-ID header processing and
caching and make sure perf record to save hit DSOs in the build-ID cache
by moving perf_session__cache_build_ids() to the end of the record__
finish_output().
