Filter out vnd.android.cursor mimetype for Picker

We don't support vnd.android.cursor mimetype,
the return result is never be expected to caller.
Ideally, we should filter that mimetype in AndroidManifest.xml,
however we currently accept */* mimetype and there is no
way to exclude a specific mimetype.
