[PATCH 4/8] apparmor: read only access to overcommit_memory

[Christian Ehrhardt <christian.ehrhardt@xxxxxxxxxxxxx>]

From: Jamie Strandboge <jamie@xxxxxxxxxx>

Allow qemu to read @{PROC}/sys/vm/overcommit_memory.
This is read on guest start-up and (as read-only) not a
critical secret that has to stay hidden.
