nl80211: Restore libnl3-route inclusion for full VLAN support with netlink

The changes in nl80211 to get rid of the libnl3-route dependency are not
sufficient to fully remove the depency from other parts of the code.
Revert the makefile related changes from that commit to avoid build
issues for cases where CONFIG_FULL_DYNAMIC_VLAN=y and
CONFIG_VLAN_NETLINK=y are used without CONFIG_DRIVER_MACSEC_LINUX=y
pulling in the needed library.
