```console
$ ln -s 'import os; os.system("echo hi")' __main__.py

lrwxrwxrwx 1 asottile asottile   31 May  5 15:55 __main__.py -> 'import os; os.system("echo hi")'
$ zip --symlinks out.zip __main__.py 
  adding: __main__.py (stored 0%)
$ python3 out.zip
hi
```

I expect the output to be similar to running `__main__.py`:

```
$ python3 __main__.py 
python3: can't open file '__main__.py': [Errno 2] No such file or directory
```

(real usecase, I wanted `__main__.py` to be a symlink but got a very strange NameError and traced it down to executing the symlink target  name instead of the symlink destination)

I tracked this down to zipimporter. I have one untested patch, when I run python from my development tree for some reason the zipimport definition at Lib/zipimport.py is not used. I assume something weird is going on because of the frozen circular imports. I would appreaciate it if someone could explain how this works and how I get the correct zipimporter definition to be used.
