pytype: suppress warnings about no 'open_binary' on importlib.resources

Fixes these pytype warnings:

    line 43, in <module>: No attribute 'open_binary' on module 'importlib.resources' [module-attr]
    line 47, in open_resource: No attribute 'open_binary' on module 'importlib.resources' [module-attr]

For some reason, I can't upgrade from 3.6.8 in my WSL environment.

Differential Revision: https://phab.mercurial-scm.org/D7681

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
