support/testing: test_ubi: allow to boot several times using the same ubi image.

Browse Source 
Since the ubi/ubifs test has been introduced, it's not possible to
boot the same ubi image twice [1]:

"TODO: if you boot Qemu twice on the same UBI image, it fails to
attach the image the second time, with "ubi0 error:
ubi_read_volume_table: the layout volume was not found"."

For some reason, the kernel corrupt the ubi image if the ubifs
rootfs is mounted with write access. Use a custom config file
to mount the rootfs readonly (vol_type=static). Doing so requires
to add the flash size (vol_size=64MiB).

At least it allows to boot several times the same ubi image.
