Revert "Merge pull request #2403 from euank/1298-runc-userns"

This reverts commit 7f3b121e061d4592729161026f18abe5444f22f0, reversing
changes made to aaaef8fa392528e6b57135a960428e9ef8b0dfbc.

I messed up and cherry-picked into master instead of the build-1298
branch and it worked because the file in question had since been renamed
to rc4.

This reverts that extraneous file.
