netdevsim: add more hw_features

netdevsim currently only set HW_TC in its hw_features, but other
features should also be present to better reflect the behavior of real
HW.

In my macsec offload testing, this ends up as HW_CSUM being missing
from hw_features, so it doesn't stick in wanted_features when offload
is turned off. Then HW_CSUM (and thus TSO, thanks to
netdev_fix_features) is not automatically turned back on when offload
is re-enabled.
