To better reflect that it became the base class for all tools, that must
be in each tool struct and where common stuff will be put.

We were still using the pathname found on the MMAP event, that could not
be the one we used when recording, so use the build-id cache for that,
only falling back to use the pathname in the MMAP event if no build-ids
are available.
With this we now also are able to do secure, seamless offline annotation.
Example:

Because 'perf record' will have to find the build-ids in after
we stop recording, so as to reduce even more the impact in the
workload while we do the measurement.
