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. Signed-off-by: Dan McGee <dan@archlinux.org>
