CI: add missing bind-mount option for /dev

The failing run-nightly-tests GitHub action is caused by a missing
bind-mount option of the /dev directory. Without the 'shared'
bind-propagation the device tree is not reliably updated within the
container. This causes newly created namespaces not to show up.
