Bug fix. add lock for GraphicsMagick function

  - DF240401-00513

[Cause]
  The crach occurs during destroying semaphore lock when
  multi-threads are processed(decoding).
  In GraphicsMagick, InitialMagick() & DestroyMagick() functions
  are not thread-safe.

[Solution]
  So locker is added for GraphicsMagick.
