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')
