Print more self-explanatory error message on bind/connect failures 

When sockets cannot be bound or connected, the existing TTCN-3 code prints
the following rather cryptic error messages:

"IPA-CTRL-IPA(47)@f70ff1fd5cfd: Dynamic test case error: Using the value of an optional field containing omit. (Transport endpoint is not connected)"

The "Transport endpoint is not connected" sort-of gives it away, but
let's make it more explicit by introducing explicit checks for the
res.connId and manual setverdict(fail) statements with proper error
message.
