[cff] s/cf2_floatToFixed/cf2_doubleToFixed/.

The new name better describes what the macro actually does;
additionally, we don't need a trailing `f' for literals (there was
only a single such instance in the code, but this caused a clang
warning because the macro itself uses `double' literals).

* src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h,
src/cff/cf2font.c, src/cff/cf2hints.c: Updated.
