selftests/net: Skip srv6_end_dt46_l3vpn_test if iproute2 too old

Browse Source 
In case iproute2 is older than version 5.14.0, released ~Sept 1, 2021,
the End.DT46 support is not available and the host_vpn_tests test contained
in the srv6_end_dt46_l3vpn_test.sh file is failing in some kernel backports.
This is the result of those tests:

################################################################################
TEST SECTION: SRv6 VPN connectivity test among hosts in the same tenant
################################################################################

    TEST: IPv6 Hosts connectivity: hs-t100-1 -> hs-t100-2 (tenant 100)  [ FAIL ]

    TEST: IPv4 Hosts connectivity: hs-t100-1 -> hs-t100-2 (tenant 100)  [ FAIL ]

    TEST: IPv6 Hosts connectivity: hs-t100-2 -> hs-t100-1 (tenant 100)  [ FAIL ]

    TEST: IPv4 Hosts connectivity: hs-t100-2 -> hs-t100-1 (tenant 100)  [ FAIL ]

    TEST: IPv6 Hosts connectivity: hs-t200-3 -> hs-t200-4 (tenant 200)  [ FAIL ]

    TEST: IPv4 Hosts connectivity: hs-t200-3 -> hs-t200-4 (tenant 200)  [ FAIL ]

    TEST: IPv6 Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200)  [ FAIL ]

    TEST: IPv4 Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200)  [ FAIL ]

To amend this, check the current running iproute2 supports the required
feature and, if not, just skip the entire test to avoid a failure.
