if lxc-init can't mount /dev/shm, don't fail.

The 'lxc-init' (a lightweight init process used by lxc-execute in place of upstart etc) tries to mount /dev/shm during startup. If that fails (for instance /dev/shm does not exist) then it aborts execution and returns -1. This is unreasonable as very few applications actually need /dev/shm.
