This fixes the problem that debug options for daemons were ignored and sets
the following behaviour for the daemons when -debug 1 is given
* start on foreground with debug ouput on the console
* do not start a sytemd unit
Starting the systemd unit in debug mode makes less sense because:
* systemd will put the daemon in the background
* systemd ignores environment variables so the only way to start
the daemon with options would be through reading a config file
tested with pveproxy, pve-ha-lrm, pve-ha-crm
