    build: remove calls to ccache in native Windows build.
    
    Anyway we disabled use of ccache in an earlier commit 2da70b3fb7 because
    of a bug in MSYS2's CPython. So there is no need to call these commands
    either. Also it seems to be breaking the 32-bit native Windows build
    (from CI log, I am unsure this is because of ccache, but the break
    happens just after running `ccache --zero-stats`).
