Allow vendor_overlay_file from vendor apex
Path to vendor overlays should be accessible to those processes with
access to vendor_overlay_file. This is okay when overlays are under
/vendor/overlay because vendor_file:dir is accessible from all domains.
However, when a vendor overlay file is served from a vendor apex, then
the mount point of the apex should be allowed explicitly for 'getattr'
and 'search'.
