    build: Fix enum generation
    
    First, drop the conditional on maintainer mode; we shouldn't rely on
    --enable-maintainer-mode to build the enums from git.
    
    Second, rework the style to fix srcdir != builddir, and avoid weird
    hardcoded tempfile names.  This newer style can be found in the
    gnome-shell git for example.
