WIN/Workaround: don't pass gid and uid to docker run call

[adswa]

A workaround in response to #138. The --user flag should now only be used when we're on a non-Windows OS.

Shall I cancel on of the CI runs?

Yes, please. It's happening because the push is to this repo rather than a fork. (I don't recall offhand whether there is a knob to prevent Travis from starting up both in this situation.)

argh, thanks for catching that! I hate notepad++. It so easy to lose/miss edits :/

Cancelled. I'll try to remember that and PR from a fork the next time.

Thanks.

Fingers crossed that on your end you can at least do this now:

$ datalad containers-add --url dhub://busybox:1.30 bb
$ datalad containers-run -n bb sh -c 'busybox | head -1'

Travis is running one job at a time, with lots of downtime in between: it's taken over 35 minutes to run two jobs whose total execution time is under 8 minutes and has yet to start the third job.

I think those two runs are sufficient for this change...
