Description

The TestKrpcSocket tests need netstat to be installed. Otherwise, they fail with:

custom_cluster/test_krpc_socket.py:109: in test_krpc_uds_address_backend_id
    rc, netstat_output, stderr = exec_process("netstat -lnt")
util/shell_util.py:43: in exec_process
    p = exec_process_async(cmd)
util/shell_util.py:54: in exec_process_async
    return Popen(shlex.split(cmd), shell=False, stdout=PIPE, stderr=PIPE)
../toolchain/toolchain-packages-gcc7.5.0/python-2.7.16/lib/python2.7/subprocess.py:394: in __init__
    errread, errwrite)
../toolchain/toolchain-packages-gcc7.5.0/python-2.7.16/lib/python2.7/subprocess.py:1047: in _execute_child
    raise child_exception
E   OSError: [Errno 2] No such file or directory

For Ubuntu, this is provided by the "net-tools" package, but that package is currently not a dependency in bin/bootstrap_system.sh. We should add it to the list. We may need an equivalent for other distributions as well.
