Subject: [PATCH v3 3/7] perf tools: Remove the logical that skip buildid cache if symfs is given

Symfs dir and buildid dir are two places that perf looks into for
symbols, currently, if symfs dir is given, buildid-cache is skipped.

In the cross-platform perf record/script scenario, we need vdsos in
buildid-cache dir and other libs in symfs dir at the same time. And
consider that the binaries indexed by buildid do not cause ambiguity,
this patch simply removes that logical.
