systemd: use standard syslog.socket unit

In systemd we now have a standard socket unit for /dev/log called
syslog.socket. This unit can be shared between an early boot mini syslog
and the full syslog implementation started later on. The mini syslog is
shipped along systemd and does nothing but simply forward the data
received through /dev/log to the kernel log buffer (i.e. kmsg, as
visible by dmesg). It is run during early boot, and then as soon as
rsyslog starts up it is terminated, so that rsyslog can take over the
/dev/log socket. Since one of the first things rsyslog does after
starting up is flushing the kernel log buffer to disk we end up with all
data from early boot up in syslog.

This patch changes two things: removes rsyslog.socket and instead
configures rsyslog.service to take possession of syslock.socket. And
secondly includes a PreStart line to terminate the running syslog bridge
instance.
