Strategy: Pass --max-redirs to #curl_headers

The default curl args in `#curl_headers` cover most of
`Livecheck::Strategy::DEFAULT_CURL_ARGS` but `--max-redirs` was
overlooked. This adds an explicit `--max-redirs` argument in
the `#page_headers` `#curl_headers` call but it's worth mentioning
that this approach wouldn't benefit from any changes in
`DEFAULT_CURL_ARGS` and would need to be manually kept in parity.
