Subject: [PATCH 3/3] fix build with musl

Add needed headers they are just not needed for glibc6+ but also
for musl
Define additional TCOPTS if not there

u_initX types are in sys/types.h be explicit about it

Upstream-Status: Pending

bh: this is a copy of the patch at the link below, modified to remove
the changes to include/libiptc/ipt_kernel_headers.h as these are
already integrated in the upstream tree. See :
