arptables: bump to 2015-05-20

This fixes building with musl and drops the dependency on the OpenWrt
kernel-header patches:

270-uapi-kernel.h-glibc-specific-inclusion-of-sysinfo.h.patch
271-uapi-libc-compat.h-do-not-rely-on-__GLIBC__.patch
272-uapi-if_ether.h-prevent-redefinition-of-struct-ethhd.patch

Use the new upstream location at netfilter.org and use a define instead
of a patch to "optimize".

Add more license tags with SPDX identifiers

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.
