selftests: drv-net: tso: fix issues with tso selftest

There are a couple issues with the tso selftest.

 - Features required for test cases are detected by searching the set
   of active features at test start, so if a feature is supported by
   hw, but disabled, the test will report that the feature under test
   is not available and fail.
 - The vxlan test cases do not use the correct ip link flags based on
   the gso feature under test
 - The non-tunneled tso6 test case is showing up with the wrong name.

With all patches applied test output is:

  # Detected qstat for LSO wire-packets
  TAP version 13
  1..14

  # Testing with mangleid enabled
