Subject: [PATCH] Bug 702985: drop use of FT_CALLBACK_DEF() def

From 2.10.3, Freetype disappeared the FT_CALLBACK_DEF() macro, which is what
we used when defining our callbacks from Freetype.

No guidance forthcoming from the Freetype developer who made those changes,
so change to explicitly declaring the callbacks file static.

Should fix the reported build failures.
