shmif: use cprng_strong32 to generate random bytes for a MAC address
cprng_fast32 sometimes returns indentical bytes, which look
"20:0e:11:33" in a MAC address, on different rump_server instances.
That leads MAC address duplications resulting in a test failure.
Fix it by using cprng_strong32 instead of cprng_fast32. However
we should rather fix cprng_fast32 (or rump itself) somehow.
The fix mitigates PR kern/54897 but test failures due to other
causes still remain.
