    gitlab-ci: Use per-build temporary directory on Windows
    
    I have seen several instances of inexplicable "Access denied" errors on Windows.
    Using per-build temporary directories avoids any chance of interference between
    builds and eliminates the possibility of temporary files leaking beyond the life
    of the build.
