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.
