perf buildid-list: No need to process the header sections again

As it is already processed by:

	perf_session__new
		perf_session__open
			perf_session__read

This was harmless, because we use dsos__findnew, that would
already find it, but is unnecessary work and removing it makes
builtin-buildid-list.c even shorter.
