Title: sdcard: Respect check_caller_access_to_name on readdir() calls

While looking at a blocked path failed as expected when trying
to access it with a stat(), read(), or getattr(), readdir() still

com.android.cts.appsecurity.AppSecurityTests#testExternalStorageWrite
by trying to interact with otherwise invisible paths.

Fixit by skipping all entries that would've been made invisible at
