units: machined needs mount-related syscalls for its namespacing operations
Specifically "machinectl shell" (or its OpenShell() bus call) is implemented by
entering the file system namespace of the container and opening a TTY there.
In order to enter the file system namespace, chroot() is required, which is
filtered by SystemCallFilter='s @mount group. Hence, let's make this work again
and drop @mount from the filter list.
