win: crashpad_util_test ProcessInfo.Handles doesn't work with CONOUT$

In 2eeaa3ac54, I added a check to make sure that the expected CONOUT$
handle was found. Its omission seemed to be unintentional. The tests
passed for me on Windows 10, but failed on the bots. I can reproduce
the failures locally on Windows 7.

Doing the inheritance test with a file other than CONOUT$ fixes the
immediate problem, but we should find out why this CONOUT$ handle isn't
showing up in the handles list on Windows 7, fix it, and add back a
test.
