This is just usbguard without the Qt GUI that brings in Qt dependencies.
Remove pandoc to reduce closure size. The usbguard build appears to
use it only for spell checking.
Remove asciidoctor because 0.7.1 switched to asciidoc. But don't add
a dependency on asciidoc, because that causes the build fails on
external DTDs.
* 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
