libopenmpt: update to 0.6.7.

### libopenmpt 0.6.7 (2023-01-08)

 *  [**Bug**] openmpt123: openmpt123 crashed on Windows 9x when showing any
    console output.

 *  IT: In sample mode, portamento to a different sample turns off the filter if
    cutoff / resonance was previously 127 / 0.
 *  S3M Detect files saved with Graoumf Tracker instead of claiming they were
    made with OpenMPT 4.47.
 *  S3M: Pattern loop state was not propagated anymore since libopenmpt 0.6.0,
    leading to wrong song length calculation and SB0 + SBx being located on
    different channels not working properly anymore.

 *  mpg123: Update to v1.31.1 (2022-11-01).
 *  FLAC: Update to v1.4.2 (2022-10-22).
 *  pugixml: Update to v1.13 (2022-11-02).
