sslutil: check for ui.insecureconnections in sslkwargs
The end result of this function is the same. We now have a more
explicit return branch.
We still keep the old code looking at web.cacerts=! a few lines
below because we're still setting web.cacerts=! and need to react
to the variable. This will be removed in an upcoming patch.
