selftests: ublk: add stripe target
Add ublk stripe target which can take 1~4 underlying backing files
or block device, with stripe size 4k ~ 512K.
Add two basic tests(write verify & mkfs/mount/umount) over ublk/stripe.
This target is helpful to cover multiple IOs aiming at same
fixed/registered IO kernel buffer.
It is also capable of verifying vectored registered (kernel)buffers
in future for zero copy, so far it isn't supported yet.
Todo: support vectored registered kernel buffer for ublk/zc.
