tests: update test-util.py for modern attrs package...

tests: update test-util.py for modern attrs package When updating to 22.1.0, this test started failing: Traceback (most recent call last): File "/tmp/mercurial-ci/tests/test-util.py", line 53, in <module> _start_default = (util.timedcmstats.start.default, 'factory') AttributeError: type object 'timedcmstats' has no attribute 'start' Poking around in `hg debugshell`, the attribute is indeed missing, but looks to be attached to `__attrs_attrs__` in both the currently vendored and the modern version of attrs. The old attrs packages will print the same for both accesses, so fingers crossed... >>> print((util.timedcmstats.start.default, 'factory')) (Factory(factory=<function timedcmstats.<lambda> at 0x000001EFDF0F21F0>, takes_self=False), 'factory') >>> print((util.timedcmstats.__attrs_attrs__.start.default, 'factory')) (Factory(factory=<function timedcmstats.<lambda> at 0x000001EFDF0F21F0>, takes_self=False), 'factory')
