Mount /dev/shm in the chroot with the right options

Bind mounting /dev/shm into the chroot isn't a good idea, as there may
be collisions and result in weird side effects.  Instead, we can just
mount a new tmpfs there, with the right options to ensure security.

(Forward ported to pending branch from 2.X Brian Dolbec)
