tweaks for wine and yarn for gui

* allow specifying a custom yarn binary for building the gui using -DYARN= cmake option
* unset DISPLAY when calling wine because i hate popups
* do not rebuild gui when building for windows
* by setting the magical undocumented env var USE_SYSTEM_7ZA to 'true' we can have the pile of npm bullshit code use our system's local 7z binary instead of the probably not backdoored binary from npm, yes for real. i hate nodejs so god damn much you have no fucking idea
* allow providing a custom gui from a zip file via -DGUI_ZIP_FILE cmake option
