We sometimes encounter connectivity issues where gitlab-shell cannot
make API calls to the Rails application. There is a self-test script
`gitlab-shell/bin/check` that tries to connect to the API; this commit
runs that script as part of `rake gitlab:check`.

Update check script in stable branch

* GitLab Shell 1.7.1 is required
* Global projects are not supported (refs #5152)
