rpc.rquotad from printing the error message "rpc.rquotad:
_svc_tli_create: could not open connection for udp6: Address family
not supported by protocol family". The error message currently ends
up in /dev/null because it is printed to stderr after calling daemon()
with noclose=0, but if the daemonization is moved to a later point to
fix the race condition of PR misc/48282, it will actually appear on
stderr and break the test, which is expecting stderr to be empty.
