Remove header Content-Encoding when archiving

Content-Encoding is a representation header which kinda means "same
content, presented differently to different clients" or "encoded
& decoded on-the-fly, guided by content negotiation".

In the case of downloading an archive, MDN docs explicitly says that
(quoted from https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Encoding):

> If the original media is encoded in some way (e.g. a zip file) then this
> information would not be included in the Content-Encoding header.

Thus this patch. Also fixes !1187.
