Fix PGPORT reassignment in ecpg regression tests

The pg_regress.sh script for ecpg regression tests checks to make
sure the port number is between 1024 and 65535. If it isn't, it uses
65432. (c310-315. This is the same behavior as the standard
regression tests, I believe.) However, it if does reassign the port
number, it was changing it back to the original, supplied port number
after creating the installation. This would cause the tests to fail
as the tests were run against a different port (the original supplied
port) while the server was listening on 65432.

This patch removes the subsequent assignment back to the original
port number. Passes both the standard regression tests and, more
importantly, those for ecpg, with normal and abnormally high port
numbers.
