Default Start rsyslogd in linuxrc.s390 like syslogging in init.c

Some tools such as NetworkManager only send messages to syslog
but not to any terminal. In order to be able to debug issues
with such tools, allow s390 to do similar logging to init.c's
built-in syslogging.

Basically, this is cherry picking with adaptation of:
0fde437ad02a7cfb170472bad0ddf3b3faf4e7b0
e8cdfc480ccec62cfb2b70598dd792bbab43a1b2
66e12bec0d1e4afeabda8ab5c0ad663cea5f8135

There have been at least the following bugs asking for the content
of /tmp/syslog on s390.
