component/caddy: Upgrade to v1.0.0-beta1

This also means that caddy source is fetched directly from upstream, as all
required fixes has been incorporated into the upstream.

Since https://github.com/mholt/caddy/releases/tag/v0.11.4 TLS-SNI challenge
is replaced by ACME TLS-ALPN challenge, so switch has changed.

Drop direct usage of gowork for now, in order to have caddy built using go
module, support for gowork with go modules might come later.
