tests: add magic string to bypass check-commit

Allow bypassing test-check-commit runs by specifying '# no-check-commit'
in the description. This should be avoided but is useful for upstream
imports such as pywatchman which will cause check-code to fail otherwise.

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