trivial diff: fix ordering bug in runtime/mercury_conf_param.h

[Zoltan Somogyi]

runtime/mercury_conf_param.h:
	Fix a bug in DJ's last change: do not test the value of the
	macro MR_STATIC_CODE_ADDRESSES before it has had a chance
	to be defined. This fix allows stack dumps and uplevel prints
	to work again.

Zoltan.
