The documentation says that when extension_control_path is set to an empty string, the default '$system' path is still assumed. However, get_extension_control_directories() added the system extension directory with a NULL macro in that case. As a result, pg_available_extensions could expose the expanded system directory path instead of reporting '$system' as the location. Record the implicitly-added system directory with the '$system' macro, so pg_available_extensions reports the documented symbolic location and does not leak the actual system path. Update the extension_control_path TAP test to check the reported location directly.
