Set libcurl options based on protocol (HTTP or HTTPS)

Today update_engine only supports HTTPS protocol. So we lock down libcurl
to use only HTTPS, set options to validate the peer certificate,
set other SSL options, etc. Moving forward, we want to support payload
downloads via HTTP also. So, this CL sets the old options only if the URL
we're using is HTTPS. If it is HTTP, we just need to lock down the protocol
to HTTP.

BUG=chromium-os:36809
TEST=Existing unit tests pass.
TEST=Manually tested downloading using HTTP and HTTPS URLs on my ZGB.
