Merge #10529: Improve bitcoind systemd service file

16be7dd Improve bitcoind systemd service file (Florian Schmaus)

Pull request description:

  Add comment how further options can be added or existing ones
  modified. Use /run/${RuntimeDirectory} for PID file.

  Remove TimeoutStopSec, TimeoutStartSec, StartLimitInterval,
  StartLimitBurst directives as those should be set indivdually.

  Remove Group to user the bitcoin user's default group.

  Changed Restart from 'always' to 'on-failure' (can also be overwritten
  individually).
