Subject: Generate a `.keep` file in `tmp` folder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A lot of scripts assumes the existence of this folder and most would fail if it
is absent.

One example of this is `rake restart` (before the previous commit) – it tries to
`touch tmp/restart.txt`, which would fail if `tmp` does not exist, which was the
case for a freshly-cloned project as `tmp` is `.gitignored` by default.

See #20299.
