netperf: insert missing blank in config
lxip: remove declaration of wait_for_continue()
lxip: fake get_random_bytes()
lxip: coding style
lxip: disable qemu check for testing (WIP)

@ssumpf please give lxip a shot under nova_x86_64 or any other 64bit
platform. After implementation of get_random_bytes(), the netperf test
actually begins but does not finish.
