Subject: [PATCH] apitrace: add enableGui option

The motivation for this change is to be able to cross-compile apitrace,
at least without the GUI. Fixing GUI cross-compilation is blocked by

Note that we also move `python3` into `nativeBuildInputs`, which is also
required to make cross-compilation work.
