Increase hard-wired timeout values in ecpg regression tests.

A couple of test cases had connect_timeout=14, a value that seems
to have been plucked from a hat.  While it's more than sufficient
for normal cases, slow/overloaded buildfarm machines can get a timeout
failure here, as per recent report from "sungazer".  Increase to 180
seconds, which is in line with our typical timeouts elsewhere in
the regression tests.

Back-patch to 9.6; the code looks different in 9.5, and this doesn't
seem to be quite worth the effort to adapt to that.
