Allow setting MX_MAX_RSS and MX_MAX_AS in rc.conf

In order to avoid DOSes due to complex MIME, MIMEDefang sets some limits on how
much memory a process can use (MX_MAX_RSS and MX_MAX_AS).

The provided example init script sets these variables to very low values (which
probably made sense when RAM was much scarcer); the port already patches that
file, increasing them, but they are still way too low in some cases, resulting
in some mail messages crashing the filter and not passing.

This patch, while retaining the current port defaults, allows these thresholds
to be set in rc.conf.
