ewah: drop ewah_serialize_native function

peff · gitster · commit 26675087a58e · 2018-06-18T10:16:19.000-07:00
We don't call this function, and never have. The on-disk
bitmap format uses network-byte-order integers, meaning that
we cannot use the native-byte-order format written here.

Let's drop it in the name of simplicity.
