[OE-core] [PATCH 1/2] busybox: don't manage sysv init script with update-alternatives

[Markus Lehtonen]

This has proved to be a bad idea. Some package srciptlet
(preinst/postinst/prerm/postrm) seems to break whatever we try to do.
Basically the failures happend because the expeceted init script is not
present when the scriptlet tries to run update-rc.d or start or stop the
service. Another indication that it is a bad idea is that no other
system service package seems to manage init scripts with
update-alternatives.

The patch also adds a new virtual package, i.e. VIRTUAL-RUNTIME_syslog.
