Avoid a deprecation warning in graphite2
...
As of graphite2 1.3.7, `gr_make_face` is deprecated in favor of
`gr_make_face_with_ops`. It's a one-liner to port over to using it.
This is potentially a compatibility break since I'm not sure when the
`with_ops` API was added, but the minimum version of graphite2 that's
supported by Harfbuzz doesn't seem to be documented anywhere anyway.

Avoid undefined-behavior
...
If a struct had (because it's a union) sizeof that is larger than the null_size,
we were providing only null_size bytes for its Null object. We know we'd never
access beyond that, but is undefined-behavior nonetheless according to the
standard.
The alternative fix would have required use of flexible-arrays, which are not
standard and have their own issues in various compiler. We've discussed that
extensively in the follow Mozilla issue (currently locked; I've asked that it
be opened):
