variants: python3both: work around portage bug that crashes if impl changes
portage can copy itself on upgrades... sometimes. However, it appears
that when switching the USE flags of portage, i.e. rebuilding a 3.12 +
3.13 build of portage to a pure 3.12 one, it starts off running with a
3.13-based portage executable, then fails with:
```
[ERROR] Exception in callback AsynchronousTask._exit_listener_cb()
handle: <Handle AsynchronousTask._exit_listener_cb()>
Traceback (most recent call last):

ModuleNotFoundError: No module named 'portage.sync.modules.rsync.rsync'

```
This could be solved by copying itself on upgrade, but it's not even
clear how that would work in the more complicated case of reinstalling a
*dependency* in the middle of the transaction.
The other solution is running portage with an EPYTHON that we know is
going to remain valid the entire time.
