Upload some update_client test files

This is related to https://codereview.chromium.org/808773005/

The idea here is that for reasons not fully understood at the moment, the
files in this CL failed the checkperms script, so 808773005 can't land.

This CL attempt to land the offending files, with two goals in mind. First,
unblock 80877300. Second, provide a clear repro for the chrome-infra team to
look at, in case something fails.

There is something going on uploading binary patches and permissions using
git cl upload.
