net/mosquitto: Update to 1.6.12

Security release.  From the changelog:

- In some circumstances, Mosquitto could leak memory when handling PUBLISH
  messages. This is limited to incoming QoS 2 messages, and is related
  to the combination of the broker having persistence enabled, a clean
  session=false client, which was connected prior to the broker restarting,
  then has reconnected and has now sent messages at a sufficiently high rate
  that the incoming queue at the broker has filled up and hence messages are
  being dropped. This is more likely to have an effect where
  max_queued_messages is a small value. This has now been fixed. Closes

  or RCE of existing file on the server running under a malicious process

apache: revisit suEXEC setup

When adding suEXEC to the apache package, Alpine's package [1] served as
a template. Not enough attention was paid to the details.

Alpine uses a different layout. So for OpenWrt to use /var/www as
DocumentRoot does not make sense. /var is also volatile on OpenWrt. This
commit removes the configure argument. The default is htdocsdir.

This also does away with uidmin/gidmin 99. The default is 100, which is
fine.

Finally, the suexec binary is moved from /usr/sbin to
/usr/lib/apache2/suexec_dir. Upstream recommends installing suexec with
"4750" (see [2]) and the group set to the user's group. While that would
be possible, it would cause a few headaches on OpenWrt. The group would
need to be changed first in a post-install script and a call to chmod
would need to be made afterward, to make the binary SUID again.

It's easier to hide the SUID binary away from others in a directory.
This way we don't need to use chmod in the post-install script.

mwan3: fix rtmon routing table function generation

If the uci option family is not set in the interface section, then there
is no default value set as in the `config_load / config_get` API.
The problem here is that if the family is not set, the default value ipv4
is normaly assumed. But the comparison fails here because the value is empty
and therefore the dedicated routing table for this interface is not compared
with the other routes from the main table and so not updated.

To fix this set the default value for this config option which is`false`
for enabled and `ipv4` for family.
