test-setdiscovery: make test compatible with chg

The test checks the output of the blackbox extension which will
contain logs corresponding to chg in case chg is running. Therefore, this
commit modifies the test to take chg into consideration while working with the
blackbox extension.

Test Plan:
Ran the test 'test-setdiscovery.t' with and without the '--chg'
option.

Differential Revision: https://phab.mercurial-scm.org/D926

This test file test the various templates related to obsmarkers.
