[m-dev.] trivial diff: fix c_header_code bug in benchmarking.m

[Fergus Henderson]

Estimated hours taken: 0.25

library/benchmarking.m:
	Fix a bug: the ML_benchmarking_dummy_word variable
	was being defined in pragma c_header_code.
	The fix is to just declare it in pragma c_header_code
	and define it in pragma c_code.
