linux-yocto/5.10: scsi-debug needs scsi-disk

It was pointed out that the default scsi-debug feature didn't behave
the same as other distros, since it doesn't have disk supporrt enabled.
We already have a disk.cfg for scsi so we include it into the debug
fragment to get the support we want.

Integrating the following commit(s) to linux-yocto/.:
