interception-tools: init at 0.1.1

The latest release of libyamlcpp in nixpkgs does not build because it uses an older version of boost than the one in nixpkgs and therefore expects a particular header file which does not exist in the latest boost anymore. For this reason, a later (git) version of libyamlcpp is used here (which actually doesn't even require boost). The substituteInPlace in the prePatch phase is needed because libevdev places its headers in non-standard places, meaning Nix cannot normally find them. The `cut` command removes the first two "-I" characters from the output of `pkg-config`. This needs to be in the prePatch phase because otherwise Nix will patch these lines to `/var/empty`, meaning you would have less specific replacement (in case other lines are also patched to `/var/empty`). I wrote the patch. (I believe it is NixOS specific.)

+Subject: [PATCH] fix udevmon configuration job path
+
+For some reason, the udevmon job $PATH seems to be empty (or otherwise
+seems to point to `/no-such-path`). This commit fixes that by setting
+its $PATH to the same $PATH that the parent udevmon process has.
