Jed Davis 09db14abce Bug 1439057 - Tighten /dev/shm access in Linux content sandbox policy. r=gcp
This patch uses the shared memory name prefixes introduced in bug 1447867
to prevent access to /dev/shm files of other applications or other
processes within the same browser instance.

When a shared memory implementation that doesn't use shm_open is available
(specifically, the memfd_create support to be added in bug 1440203),
/dev/shm access is completely denied.
