Update all .py source files by
$ pyupgrade --py3-only $(git ls-files | grep ".py$")

When a context's 'capabilities' property was a non-empty list,
Daemon.run() would try to manipulate Linux capabilities, and fail if the
original user didn't already have (at least) these capabilities. This
is appropriate for the regular use case, but the intention of
UnprivilegedPrivsepFixture is that it would be a no-op that works for
zero-privilege test environments.
This change clears the capabilities list (setting/expecting zero
privileges) in UnprivilegedPrivsepFixture, as was originally intended.

keys (see test_comm.py).
