trivial diff: fix mdb bug with detailed stack traces

[Fergus Henderson]

Fix a bug that was causing mdb's detailed stack traces to come out
incorrectly on some occaisions.  (The test case for this bug fix is
tests/debugger/queens.)

runtime/mercury_stack_trace.c:
	Fix a bug: `maybe_from_full' should have type `Integer', not `Word'.
