[Buildroot] [git commit branch/2017.02.x] busybox: don't remove S01logging when CONFIG_SYSLOGD is disabled

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a06bf88dcae4cf6d9b7f3a02b9abdbc60eab51b2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

The current busybox.mk explicitly removes S01logging if CONFIG_SYSLOGD
is disabled in the Busybox configuration. However:

 - This causes the removal of the S01logging script potentially
   installed by another package (currently syslog-ng, rsyslog and
   sysklogd can all install a S01logging script).

 - We generally don't try to clean-up stuff that we may have installed
   in a previous make invocation and that is no longer needed
   following a configuration change.

Fixes bug #10176
