[PATCH:libXfont 5/5] Don't build unused code in bitmapfunc.c if all bitmap formats are disabled

[Alan Coopersmith]

If the only bitmaps we support are builtins, don't need the code to
register all the bitmap font file handlers.

Fixes gcc warnings:
bitmapfunc.c:110:1: warning: 'BitmapOpenBitmap' defined but not used [-Wunused-function]
 BitmapOpenBitmap (FontPathElementPtr fpe, FontPtr *ppFont, int flags,
 ^
bitmapfunc.c:155:1: warning: 'BitmapGetInfoBitmap' defined but not used [-Wunused-function]
 BitmapGetInfoBitmap (FontPathElementPtr fpe, FontInfoPtr pFontInfo,
 ^
