net-test: add 'random.trust_cpu=on' to kernel command line
Another workaround for boot time entropy starvation,
which is only usable on sufficiently new kernels.
While we could just enable CONFIG_RANDOM_TRUST_CPU=y instead of passing
another thing via kernel commandline, this would only take effect for
kernels we build ourselves - ie. for UML builds and not for gki/cuttlefish
pre-built kernels.
Test: passed
