Subject: [PATCH] perf tools: Factor out buildid reading and make it implicit
 in dso__load

If we have a buildid, then we never want to load an image which has no buildid,
or which has a different buildid, so it makes sense for the check to be built
into dso__load and not done separately.  This is fine for old distros which
don't use buildid at all since we do no check in that case.

This refactoring also alleviates some subtle race condition issues by not
opening ELF images twice to check the buildid and then load the symbols, which
could lead to weirdness if an image is replaced under our feet.
