pgsql: Update ssl test certificates and keys

Update ssl test certificates and keys

Debian testing and newer now require that RSA and DHE keys are at
least 2048 bit long and no longer allow SHA-1 for signatures in
certificates. This is currently causing the ssl tests to fail there
because the test certificates and keys have been created in violation
of those conditions.

Update the parameters to create the test files and create a new set of
test files.
