Improve bitcoind systemd service file
Improve bitcoind systemd service file

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).
