The config variable OVERLAY_MOUNT_OPTIONS is used to configure
the overlay mount options when running ./check -overlay.
The config variable MOUNT_OPTIONS is used to configure the
mount options for base fs.
If config sets value of OVERLAY_MOUNT_OPTIONS and
does not set MOUNT_OPTIONS, the value of MOUNT_OPTIONS
may be leftover from previous _overlay_config_override, so
don't use that value for base fs mount.
