The newest Linux stable kernel releases:
* v5.10.205
* v5.15.144
* v6.1.69
received a backported version of commit 1f5020acb33f ("net: vlan: introduce
skb_vlan_eth_hdr()"). batman-adv must therefore not provide this function
any longer for these kernel versions.

OpenWrt master is no longer providing any kernels older than 5.15. Just
drop the compat-hacks/patches for older kernels to make it easier to
maintain the package.
