Fix the condition for HAVE_QTKIT.

    The AM_CONDITIONAL call for HAVE_QTKIT has had a bug since
    3ddb9e51, where a 'test' invocation was elided. On MacOS X
    10.7.2 this caused the configure script to hang with an
    obscure launchd message:

      launch_msg("CheckIn") IPC failure: Operation not permitted

    This patch restores the intended logic.
