Fix missing builtin aliases on Python 2 (and other versions) #6441

Some builtin aliases (like typing.ChainMap) are not available on some Python versions, or in some fixtures. However, if while they were first looked up while target namespace was incomplete, we put a PlaceholderNode in typing. This PR either doesn't put or removes this placeholder node if we didn't find the target after the target namespace is complete.

I didn't find a way to test this (since we don't have incremental pythoneval tests), but I double-checked this fixes the crash with actual Python 2 stubs.
