perf tools: Set build-id using build-id header on new mmap records
MMAP records that occur after the build-id header is parsed do not have
their build-id set even if the filename matches an entry from the
header. Set the build-id on these dsos as long as the MMAP record
doesn't have its own build-id set.
This fixes an issue with off target analysis where the local version of
a dso is loaded rather than one from ~/.debug via a build-id.
