[m-dev.] trivial diff: fix bug in my last change to library/io.m

[Fergus Henderson]

library/io.m:
	Fix a bug in my previous change to io.m: now that the C code for
	io__make_temp can call mercury_io_error() to throw an exception,
	it must be declared `may_call_mercury' rather than
	`will_not_call_mercury'.
