AppArmor default config blocks Snowflake from running with system tor

(This isn't a problem with Snowflake itself so putting Core Tor as component.)

Steps to reproduce:

  1. Copy paste snowflake-client inside /Browser/TorBrowser/Tor/PluggableTransports to /usr/bin.
  2. Add UseBridges 1, ClientTransportPlugin snowflake exec /usr/bin/snowflake-client, as well as Bridge snowflake 0.0.3.0:1 2B280B23E1107BB62ABFC40DDCC8824814F80A72 to torrc.
  3. sudo service tor restart
  4. Looking at the task manager I don't see that snowflake is running as a process, this most likely means that it was blocked from launching due to the AppArmor profile distributed with Tor.

OS: Ubuntu 17.10. /etc/apt/sources.list has Tor Project repositories. Also Tor 0.3.2.x-alpha that was used when testing.
