[PATCH 2/4] overlay: use default overlay mount options _overlay_mount_dirs()

[Amir Goldstein <amir73il@gmail.com>]

Tests that use _overlay_mount_dirs() should also use the
default overlay mount options.
Move mount options from overlay_mount() into _overlay_mount_dirs()
and use helper common_dev_mount_opts() to get options.

OVERLAY_MOUNT_OPTIONS is assigned to MOUNT_OPTIONS, so
there is no need to use OVERLAY_MOUNT_OPTIONS directly.

Use common_dev_mount_opts in _overlay_mount_dirs()
