    Disable the SIG(0) checks quota in the sig0 test

    named releases the SIG(0) quota only after the query callback, which
    already sent the response, returns.  test_sig0_hmac sends its second
    query right after reading the first answer, so under slow builds
    (TSAN) the second query can find the default quota of 1 still taken
    and get REFUSED instead of SERVFAIL.  None of the sig0 tests exercise
    the quota itself.
