If a system is configured to allocate hugepages on boot, systemd will automatically present a hugetblfs at /dev/hugepages
This is not compatible with the current apparmor profile which expects presentation at /var/run/hugepages.

==============================================
SRU Justification
Impact: libvirt unable to grant access to hugepages
Fix: add an apparmor rule to allow libvirt to access hugepages at the path which systemd uses
Test case: boot a vm with hugepages enabled.
Regression potential: We already have an allow rule for the old hugepages mount path, we are only allowing access to the path which systemd uses. So there should be no regressions.
