tests: pbr is not working properly on arm 4.9 kernels

Just disable pbr tests on anything less than 4.10.

This has to do with the fact that the arm platform
is not allowing us to install a route into a
non default table using a interface associated
with a vrf.

ip route add default 4.5.6.7 via swp39 table 10000

When swp39 is in a vrf other than default
