ppp: include netinet/in.h before linux/in.h in pppoe.h

The patch ppp-fix-building-with-linux-4.8.patch tries to fix build error
with 4.8 or newer linux headers, but it would break building with kernel
< 4.8. There is a better solution to fix this issue in upstream.
Backport the upstream patch and replace the old one.

+Subject: [PATCH] pppoe: include netinet/in.h before linux/in.h
+
+This fixes builds with newer kernels. Basically, <netinet/in.h> needs to be
+included before <linux/in.h> otherwise the earlier, unaware of the latter,
+tries to redefine symbols and structures. Also, <linux/if_pppox.h> doesn't work
+alone anymore, since it pulls the headers in the wrong order, so we better
+include <netinet/in.h> early.
+
+Upstream-Status: Backport
