Subject: [PATCH v1] Fix an issue in PostgreSQL::Test::Cluster:psql()

Due to the commit c5385929 which made all Perl warnings to fatal,
use of PostgreSQL::Test::Cluster:psql() and safe_psql() with
timeout started to fail with the following error:

Use of uninitialized value $ret in bitwise and (&) at
..src/test/perl/PostgreSQL/Test/Cluster.pm line 2015.

Fix that by placing $ret conversion code in psql() in an
if (defined $ret) block.

With this change, the behavior of psql() becomes same as before,
that is, the whole function returns undef on timeout, which is
usefully different from returning 0.
