Add a selftest under tools/testing/selftests/drivers/net/rss_key.py
checking both the host RSS key (/proc/sys/net/core/netdev_rss_key) and
the RSS key, indirection table, and flow-hash layouts reported by a
device over ethtool netlink.

When invoked without NETIF, NetDrvEnv creates a 4-queue netdevsim device,
which calls netdev_rss_key_fill() and allows exercising both the host key
and the netlink RSS reporting path in a virtual machine without special
hardware. When invoked with NETIF, it checks the key and indirection
table of that interface.
