nixos/usbguard: create package and module (#28363)

* nixos/usbguard: create package and module

No usbguard module or package existed for NixOS previously. USBGuard
will protect you from BadUSB attacks. (assuming configuration is done
correctly)

* nixos/usbguard: remove extra packages

Users can override this by themselves.

* nixos/usbguard: add maintainer and fix style
