trivial diff: fix SICStus syntax error

[Fergus Henderson]

The right fix would be to disable all the Prolog support,
but that's a tad trickier, so this will do for now...

Estimated hours taken: 0.1

library/std_util.m:
        Add parentheses to use of `some' in type declaration for has_type/2,
	to avoid syntax error for SICStus Prolog.
