Some python modules rely on "import cmake".

Only build and ship the python parts, and don't download and
build cmake from sources. Use the already built cmake instead.

The CMakeLists.txt file is a crippled copy from this cmake
python module's sources, removing almost everything, and
adding a dummy install target, so do_install() doesn't fail.

The python code is patched so cmake is used from PATH.
