package/xtables-addons: bump to version 3.4

Add hash for LICENSE.

This version works with linux kernel 5.0 and newer. It requires
CONFIG_NF_NAT enabled in the kernel configuration, otherwise it fails
to build:

ERROR: "nf_nat_setup_info" [/home/thomas/projets/buildroot/output/build/xtables-addons-3.4/extensions/xt_DNETMAP.ko] undefined!

[Thomas: enable CONFIG_NF_NAT in the kernel configuration.]
