Please allow procmail 3.22-10 in testing

procmail (3.22-10) unstable; urgency=low

  * Modified autoconf to hardcode 127.0.0.1 as the address for localhost,
    instead of taking the value from the machine on which the package is
    being built. Reported by Stephen Frost. Closes: #283529.

Not a dangerous change. It is even possible that the produced
executables are "the same" as in 3.22-9.

Thanks.
