[libvirt] [PATCH] apparmor: add ro rule for sasl GSSAPI plugin on /etc/gss/mech.d/

[Christian Ehrhardt]

If a system has sasl GSSAPI plugin available qemu with sasl support will
try to read /etc/gss/mech.d/.

It is required to allow that to let the modules fully work and it should
be safe to do so as it only registers/configures plugins but has no secrets.
