compat: Use skb_vlan_tag_present() instead of vlan_tx_tag_present()

Since RHEL6 provides it as preprocessor define and does not provide
vlan_tx_tag_present(). Add defines in case of vlan_tx_tag_present()
isn't available to back tc_skb_protocol() to old behaviour before
commit d8b9605d2697 ("net: sched: fix skb->protocol use in case
of accelerated vlan path").
