feat(tazjin/tverskoy): Enable automatic screen locking

Browse source 
Defines a small helper script that resets the keyboard layout (to
avoid getting stuck in Russian layout) and locks the screen via
xsecurelock, and configures home-manager to launch this automatically.

Fascinatingly this actually seems to be capable of locking the
screen *on suspend*, not *after suspend*.
