pg_recvlogical: Add tests for output file permissions

Browse source 
Commit 263d1e6dfe changed pg_recvlogical to honor source cluster file
permissions when creating output files. This commit adds tests verifying
that output files are created with mode 0600 when the source cluster is
initialized without group access, and with mode 0640 when group access is
enabled.
