Stop trying to set NOATIME mount flag because kernel will soon disallow this.

The kernel devs have decided it's a security vulnerability for apps to be able to change the atime settings on private bind mounts of filesystems they don't own. Unfortunately instead of just ignoring the offensive flag, mount() will fail.

supervisor-main: Fix nodev oddity in Linux 3.17

nodev on new tmpfs mounts in a non-root userns.  This means that
remounting without nodev will fail now that the lock bits work
correctly.
