selftests: forwarding: bridge_mdb_max: Check iproute2 version

Browse source

commit 6bdf3d9765 upstream.

The selftest relies on iproute2 changes present in version 6.3, but the
test does not check for it, resulting in errors:

 # ./bridge_mdb_max.sh
  INFO: 802.1d tests
  TEST: cfg4: port: ngroups reporting                                 [FAIL]
          Number of groups was null, now is null, but 5 expected
  TEST: ctl4: port: ngroups reporting                                 [FAIL]
          Number of groups was null, now is null, but 5 expected
  TEST: cfg6: port: ngroups reporting                                 [FAIL]
          Number of groups was null, now is null, but 5 expected
  [...]

Fix by skipping the test if iproute2 is too old.
