sdk-manual: extensible.rst: remove confusing post-install-logging

This is a fix for 22dc5b3be3b1fbdb9447999b71f79db055271826, which has
completely replaced debug-tweaks. But in the context of devtool ide-sdk
and the comment in the example, the post-install-logging-image feature
doesn't really make much sense. Therefore, remove it.
