[tor-commits] [tor/release-0.4.0] test/circuitpadding: Delete circuitpadding_circuitsetup_machine()
commit 387d9448de4c5044800706b4ed21b48b4426cb7e
Author: teor <teor@xxxxxxxxxxxxxx>

test/circuitpadding: Delete circuitpadding_circuitsetup_machine()
This test was disabled in 0.4.0 and later, but the fix in #29298 was only
merged to 0.4.1. So this test will never be re-enabled in 0.4.0.
Part of 29500.
