Windows camera: drop Thread.setDaemon (not in the ParparVM runtime)

The clean (ParparVM) target has no java.lang.Thread.setDaemon, so the translated
WindowsCameraImpl.c failed to compile (undeclared virtual_java_lang_Thread_setDaemon).
The takePhoto worker exits as soon as the frame is captured, so a non-daemon thread
is fine.
