Subject: [PATCH] Workaround Windows bug discovered with Go security fix

For context: https://github.com/golang/go/issues/15286

This commit downloads go1.5.3 in addition to go1.5.4 in order to
workaround the issue.

It is not expected to do a Docker release without a proper fix, however
this should help unblock Docker development on Windows TP5.
