automation: update packages in requirements files

We like keeping up to date. The content of the autogenerated files
changed slightly because I used a newer version of `pip-compile`
than what was used previously.

Differential Revision: https://phab.mercurial-scm.org/D6714

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