Remove BOM from SkFontHost_FreeType.cpp.

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>

We don't want UTF-8 BOM in source files. I actually 1gtm'ed the original CL, but
failed to notice that it introduced the BOM.
