iptables: bump to version 1.6.0

Browse Source 
Add option for nftables compat utilies and for bpf compiler/nfsynproxy
configuration tool.

Drop symlink trickery since it's not required any more.

Switch homepage to proper one and drop the kernel v2.4+ note since
that's not supported by buildroot anyway.

Drop most patches (except musl build) since they're upstream.

Subject: iptables: link against libnetfilter_conntrack
Linking currently fails in --enable-static case:
../extensions/libext.a(libxt_connlabel.o): In function `connlabel_get_name':
iptables/extensions/libxt_connlabel.c:57: undefined reference to `nfct_labelmap_get_name'
[..]
It's libxtables.la(libxt_connlabel.o) using libnetfilter_conntrack.
If libnetfilter_conntrack is not found, @libnetfilter_conntrack_CFLAGS@
and @libnetfilter_conntrack_LIBS@ (and their ${} ones) should be empty,
therefore producing no harm to include unconditionally.

Subject: [PATCH 1/3] consistently use <errno.h>
On glibc, <sys/errno.h> is a synomym for <errno.h>.
<errno.h> is specified by POSIX, so use that.
Fixes compilation error with musl libc

Subject: [PATCH 2/3] include: remove libc5 support code
Current code makes the assumption that !defined(__GLIBC__) means libc5
which is very unlikely the case nowadays.
Fixes compile error because of conflict between kernel and musl headers.
