perf annotate: Fix symbolic link of build-id cache
The commit 6ebd2547 ("perf annotate: Fix a bug following symbolic link of a build-id file") changed to use dirname to follow the symlink. But it only considers new-style build-id cache names so old names fail on readlink() and force to use system path which might not available. Signed-off-by:Namhyung Kim <namhyung@kernel.org> Acked-by:
