Fix more compiler warnings.

Reported by Wojciech Mamrak <wmamrak@gmail.com>.

* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
Make integer constant unsigned.

* src/sfnt/ttsbit.c (tt_face_load_strike_metrics)
<TT_SBIT_TABLE_TYPE_SBIX>: Fix types.
(tt_sbit_decoder_load_compound, tt_face_load_sbix_image): Add proper
casts.
