Subject: [PATCH] Revert a sysrc to an echo as it due to invalid characters.

When running
    sysrc -f /etc/sysctl.conf net.inet.ip.fw.verbose_limit=5

it throws the following error:

    sysrc: net.inet.ip.fw.verbose_limit: name contains characters not allowed in
shell

Fix this by reverting to using an echo to add the sysctl to sysctl.conf.
