selftests: net: dsa: symlink the tc_actions.sh test

This has been validated on the Ocelot/Felix switch family (NXP LS1028A)
and should be relevant to any switch driver that offloads the tc-flower
and/or tc-matchall actions trap, drop, accept, mirred, for which DSA has
operations.

TEST: gact drop and ok (skip_hw)                                    [ OK ]
TEST: mirred egress flower redirect (skip_hw)                       [ OK ]
TEST: mirred egress flower mirror (skip_hw)                         [ OK ]
TEST: mirred egress matchall mirror (skip_hw)                       [ OK ]
TEST: mirred_egress_to_ingress (skip_hw)                            [ OK ]
TEST: gact drop and ok (skip_sw)                                    [ OK ]
TEST: mirred egress flower redirect (skip_sw)                       [ OK ]
TEST: mirred egress flower mirror (skip_sw)                         [ OK ]

TEST: trap (skip_sw)                                                [ OK ]
