selftests/bpf: fix xdp_redirect xdp-features selftest for veth driver

Browse source 
xdp-features supported by veth driver are no more static, but they
depends on veth configuration (e.g. if GRO is enabled/disabled or
TX/RX queue configuration). Take it into account in xdp_redirect
xdp-features selftest for veth driver.

Fixes: fccca038f3 ("veth: take into account device reconfiguration for xdp_features flag")
