Consolidate const_casts<> in FXFT_Get_Name_Index()

There's a missing const in a qualifier in the third party FT library
header, so rather than casting on every invocation, consolidate these
into our wrapper macro. This may be easier to remove should the API
ever get corrected.

Part of the war on const_cast<>.
