Avoid compiler warning in image.c

* src/image.c (image_can_use_native_api): Avoid compiler warnings
by making this function conditioned on HAVE_NATIVE_IMAGE_API.
(initialize_image_type): Call image_can_use_native_api only if
HAVE_NATIVE_IMAGE_API is non-zero.  Reported by Basil
L. Contovounesios <contovob@tcd.ie>.
