cleanup $HOME while building docker image?

[yarikoptic]

Was surprised to find that fmriprep provides its own $HOME, which is I guess a good thing in general although interferes with my "reproducible interactive shell session" effort in ReproNim/containers#9 .

But that HOME comes with npm caches etc which I guess are not needed and could be safely removed?

I'm assuming this means cleaning up .npm, .conda and .empty?
