fsmonitor: change the distance calculation

Change the distance calculation in the fsmonitor extension. It is done
in a method since anticipated changes will need to use this logic as well.

Test Plan:
Tested on development server.

Differential Revision: https://phab.mercurial-scm.org/D988

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