Do not purge /etc/rsyslog.d

Remove the default /etc/rsyslog.d/50-default.conf config file created by
the rsyslog package instead of completely purging the /etc/rsyslog.d/
directory. Purging will remove all the config files added by other
packages (the haproxy package adds /etc/rsyslog.d/49-haproxy.conf for
example).
