package/rsyslog: drop libee dependency

Extract from
https://github.com/rsyslog/rsyslog/commit/1bc60d4ba29053bd54dd11de46e985f1d34d8462:

"NOTE TO MAINTAINERS: libee is not used by rsyslog for quite some while.
However, we never included this info into the changelog. So if you still
make rsyslog depend on libee (some do this), you should stop doing so
now. Libee is dead and no longer been maintained nor hosted by us."
