Subject: [PATCH v7 07/15] bugreport: add git-remote-https version

From: Emily Shaffer <[email-masked]>
Date: Thu, 13 Feb 2020 17:53:35 -0800

It's possible for git-remote-curl to be built separately from git; in that
case we want to know what version of cURL is used by git-remote-curl, not
necessarily which version was present at git-bugreport's build time.
So instead, ask git-remote-curl for the version information it knows
about.

Today, "git-remote-http" and "git-remote-https" are aliased to
"git-remote-curl"; but in case we rely on a different library than cURL
in the future, let's not explicitly reference cURL from bugreport.

For longevity purposes, invoke the alias "git-remote-https" instead of
"git-remote-http".

Since it could have been built at a different time, also report the
version and built-from commit of git-remote-curl alongside the cURL info.
