perf tools: Fix annotation with kcore
Patch "perf tools: Fix build-id matching on vmlinux" breaks annotation with kcore. The problem is that symbol__annotate() first gets the filename based on the build-id which was previously not set. This patch provides a quick fix, however there should probably be only one way to determine the filename. e.g. symbol__annotate() should use the same way as dso__data_fd().
