[LTP] [PATCH v2] ipsec_lib.sh: check ip_vti/ip6_vti are enabled or skip tests

[Radoslav Kolev]

In network stress test groups there are tests expecting
CONFIG_NET_IPVTI/CONFIG_IPV6_VTI to be enabled in the kernel,
and if it's not they fail. There is a check for VTI support in
the ip utility, but not for the kernel. Skip these tests if
there is no ip_vti/ip6_vti support in the kernel.
