ext/dba/tests/gh16390.phpt: skip if inifile is disabled

This test reads an ini "file" from a string, and expects a warning
about locking. But if inifile support is disabled, then you'll get

  Warning: dba_open(): Handler "inifile" is not available in
  /path/to/ext/dba/tests/gh16390.php on line 3

instead. We skip the test if inifile support is disabled.

Closes phpGH-17011.
