PR fortran/71706 - ICE on using sync images with -fcheck=bounds

The run-time checking code did not properly convert the kind of the
argument to SYNC IMAGES, leading to an error in verify_gimple.  Fix that.

gcc/fortran/
	PR fortran/71706
	* trans-stmt.c (gfc_trans_sync): Do proper kind conversion in
	bounds-checking code.
