Jonathan Afek bb04a9a9a3 tests: Use general cmd_execute() for bridge setup commands 
The hwsim tests used to execute shell commands in the tests using the
subprocess python module. Use the cmd_execute() general function for
executing shell commands to setup bridge so that this would also work on
remote setups.
