Subject: [PATCH] curl: Enable decoding from server's Content-Encoding

I would like to consume RAUC bundles straight from our CI environment
which uses OpenStack Swift as a backend for artifact storage, and
OpenDev's Zuul as the CI runner. As it happens, our CI jobs sends file
content to Swift with a Content-Encoding: gzip [1], and Swift appears to
always send the file with that Content-Encoding no matter what
Accept-Encoding the HTTP client sends in their request.

This patch simply uses curl's list of default supported Content-Encoding
decoders (that's the special magic "" value of this header). The end
result is that our boxes can now fetch stuff from our CI environment
without any problems.
