download-from-binary-cache: Use HEAD requests if possible
In "nix-env -qas", we don't need the substitute info, we just need to know if it exists. This can be done using a HTTP HEAD request, which saves bandwidth. Note however that curl currently has a bug that prevents it from reusing HTTP connections if HEAD requests return a 404: https://sourceforge.net/tracker/?func=detail&aid=3542731&group_id=976&atid=100976 Without the patch attached to the issue, using HEAD is actually quite a bit slower than GET.
