community/bitcoin: update to 0.14.0 / use supervise-daemon

https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.14.0.md

initd now uses supervise-daemon for service supervision.

please note the new bitcoin.conf format => do NOT enable daemon mode
as supervise-daemon requires services to run in the foreground.
