deps: avoid redirect with eclipse gitlab

Use ".git" at the end of gitlab URLs to avoid the redirects, e.g.:

  warning: redirecting to https://gitlab.eclipse.org/eclipse/titan/titan.ProtocolModules.M3UA.git/

This is not just a cosmetic improvement that gets rid of these warnings,
but it actually has the effect that we make less requests to the gitlab
eclipse server and are less likely to trigger the rate limiting. On my
machine I do trigger it with "make deps" without this patch, and with
this patch I don't.
