match: make _donormalize's auditor and warn arguments optional

Argument 'warn' is actually non-required, since there's a 'if warn:'
check before usage. Argument 'auditor' is passed to
pathutil.canonpath(), in which it is optional.

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