[PATCH perf/core v5 03/15] perf-buildid-cache: Use lsdir for looking up buildid caches

[Masami Hiramatsu]

From: Masami Hiramatsu <masami.hiramatsu...@hitachi.com>

Use new lsdir() for looking up buildid caches. This changes
logic a bit to ignore all dot files, since the build-id
cache must not start with dot.
