When DefaultSelector is used on VMware ESXi, it fails with 

>>> import selectors
>>> selector = selectors.DefaultSelector()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/build/mts/release/bora-4887370/bora/build/esx/release/vmvisor/sys-boot/lib64/python3.5/", line 390, in __init__
OSError: [Errno 38] Function not implemented

After debugging, I found that it is using Selector which is not implemented for ESXi kernel. 

Change DefaultSelector mechanism to use 'select' implementation to choose default selector.

Łukasz, what do you think of backporting this to 3.9?

This is a bit of a risky change looking at the PR but since it's a bugfix, we should have it for 3.9.0rc1.
