runtime-rs: Configure s390x specific flags for Makefile

Browse Source 
s390x supports a different machine type `s390-ccw-virtio` and it is
not required to configure cpu features by default for the platform.
A hypervisor `dragonball` is not supported on s390x so that `DBCMD`
is not necessary. `vm-rootfs_driver` should be set to `virtio-blk-ccw`.
This commit is to set the architecture-specific flags for Makefile.

Fixes: #9158
