Remove sfnt dependency from xps gyp tartget.

Remove sfnt dependency from xps gyp tartget.

The xps gyp target depends on skia_lib, which in turn contains
the sfnt target (and re-exports it settings). As a result, it
should not separately depend on the sfnt target. This currently
isn't causing issues because the sfnt target is mostly header only,
but any code in it may be duplicated.

Things outside skia_lib should depend on skia_lib and not directly on anything
inside skia_lib.
