Remove BOM from SkFontHost_FreeType.cpp.

With r12822 a UTF-8 BOM was added to SkFontHost_FreeType.cpp.
This change removes it.

Running

find . -type f \( -name '*.cpp' -o -name '*.h' \) -exec file {} \; | grep BOM

makes it look like this is the only file with a UTF-8 BOM at this time.
The BOM is easily removed with

tail -c +4 <filename>
