Subject: [PATCH 1/2] teeworlds: add buildClient feature flag

Allows for only building the Teeworlds server (for example, in a
headless environment). This gets rid of a great deal of dependencies
which would be unneccessary in a headless server.

Also added the package "teeworlds-server" in all-packages.nix, defined
as an override.
