[LTP] [PATCH v1] lib/tst_test.sh: skip test if ip returns "Error: Unknown device type"

[Radoslav Kolev]

In network stress test groups there are tests expecting
CONFIG_NET_IPVTI 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 vti device type is not known by
the kernel.
