Revert "endpointsynchronizer: do not delete CEP when endpoint is deleted"

This reverts commit 8068f1a91f043c26ecdc15ad78fe6878a8fc8957.

This reverted commit introduces a regression where Cilium Endpoints can
be left around after the Cilium Endpoint was locally deleted. Although
it was a scale optimization for non existing docker images, the security
aspect will overlap the scalability concern initially thought.
