Install git and ccache, and configure OpenMP support for cmake.

Might want to consider GGML_CCACHE=OFF instead of installing ccache inside the docker build. It gets you nothing in those isolated builds, as nothing will be cached.

I'm also using this image as the build base for our internal CI, so ccache will be utilized there as well.
