Jason A. Donenfeld 3dbc5fdacb target/s390x: support PRNO_TRNG instruction 
In order for hosts running inside of TCG to initialize the kernel's
random number generator, we should support the PRNO_TRNG instruction,
backed in the usual way with the qemu_guest_getrandom helper. This is
confirmed working on Linux 5.19.
