[gimp/wip/Jehan/native-win64-build] build: drop ccache entirely.

commit 3948ded00e85cb0b6a54f8f5cf9e0aead4a4fa77

    build: drop ccache entirely.
    
    It doesn't look our cache is actually reused. The build ends with the
    message:
    
    > No URL provided, cache will be not uploaded to shared cache server.
    > Cache will be stored only locally.
    
    Let's just see with no ccache at all.
