selftests: drv-net: test drivers sleeping in ndo_get_stats64
Most of our tests use rtnetlink to read device stats, so they don't expose the drivers much to paths in which device stats are read under RCU. Add tests which hammer profcs reads to make sure drivers: - don't sleep while reporting stats, - can handle parallel reads, - can handle device going down while reading. Set ifname on the env class in NetDrvEnv, we already do that in NetDrvEpEnv.
