libvirtd.conf is for the general daemon configuration.

The QEMU driver has a separate /etc/libvirt/qemu.conf which is
read by qemudLoadDriverConfig() into struct qemud_driver. The
code for this is in src/qemu_conf.c 

The security driver is really more of a generic resource though,
that we could use in several drivers, so another alternative
is an /etc/libvirt/svirt.conf loaded the svirt driver. In any
case look at the qemudLoadDriverConfig() for example of the API
usage for config files
