    build: Do not call gtk_init()
    
    It needs to open a display connection, which is obviously going to fail
    miserably on any headless build machine.
    
    Instead, we need to find where we started requiring to initialize GTK
    when calling a get_type() function, and stop doing that.
    
    This commit and commit 15cc85db295b3d54f85c541b3c82d7b703c851c8 fully
    revert commit 6838861d26bfec9af53438022bd1f5b60bab3bf4.
