tests: import CPython's hostname matching tests

CPython has a more comprehensive test suite for it's built-in hostname
matching functionality. This patch adds its tests so we can improve
our hostname matching functionality.

Many of the tests have different results from CPython. These will be
addressed in a subsequent commit.

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