tests: add hghave rule 'setprocname' to check if osutil.setprocname and use it

setprocname is not present when we build a pure version. This leads to output
changes in test-chg.t

This should make test suite green on Python 2 pure build with chg.

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