largefiles: replace invocation of os.path module by vfs in overrides.py

This commit is part of bigger effort described in 'Windows UTF-8' plan.
It is not changing all invocations but the ones where change is
obviously correct and doesn't require complicated changes.

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