[PATCH] gdiplus/tests: Don't fail if fonts are missing

[Vincent Povirk]

Apologies for taking so long to get to this. I'm still dealing with
health problems.

I'm concerned that this will make the tests succeed with missing fonts
on Windows, and the various name variables will be used uninitialized
(which would've happened before, but only when the tests were
failing). Maybe a todo_wine ok(0) and a return in the missing fonts
case would solve that.

It'd be nice to hear from the winetest maintainer about this case. In
other cases, we've made the decision that the tests should fail if an
API breaks because optional dependencies are missing. I don't know
that we officially have a dependency on those fonts, but API's are
breaking because they are missing.
