Clean up libfetch checking in configure

Model it after the new OpenSSL check, and have it be a bit more useful. If
you do not explicitly pass a command line option, it will be linked if
available but will not error out if it is missing. Also bump the version to
that where connection caching was introduced as we use these new features in
the codebase.
