[m-dev.] diff: move var definition from header file

[Fergus Henderson]

Estimated hours taken: 0.5

runtime/mercury_stack_trace.h:
runtime/mercury_stack_trace.c:
	Fix a bug: MR_stack_trace_bottom and MR_nondet_stack_trace_bottom
	were being _defined_ in the header file.  I changed it so that
	they were only _declared_ in the header file, and defined in the
	.c file.
