* Use universal binary for Tor tests
The test data binary at brave/test/data/tor/components/mac/cldoidikboihgcjfkhdeidbpclkineef/1.0.0/tor-0.3.3.8-darwin-brave-5 is x86_64 only.
But the component is a universal binary: cldoidikboihgcjfkhdeidbpclkineef
Tor tests BraveTorBrowserTest and BraveTorWithCustomProfileBrowserTest are failing with EBADARCH.
* Ensure component cleanup finishes before test exits
When PRE_ResetBridges sets bridges to not used, it triggers cleanup of the pluggable transport component. The test was only waiting for the snowflake process to exit (WaitProcessExit), but the component cleanup happens asynchronously on a separate thread
