Add nodev Option to /dev/shm

An XCCDF Rule

Description

The nodev mount option can be used to prevent creation of device files in /dev/shm. Legitimate character and block devices should not exist within temporary directories like /dev/shm. Add the nodev option to the list of Options in the systemd.mount unit that controls mounting of /dev/shm.

Rationale

The only legitimate location for device files is the /dev directory located on the root partition. The only exception to this is chroot jails.
