perlcritic: disable policy prohibiting no strict

We require modules to use strict. Using no strict is already a signal
that we are doing something abnormal, and generally doesn't have any
alternatives. This would force disabling strict, then silencing the
critic rule about disabling strict. Needing a second signal for the same
thing is pointless.
