[PATCH] uapi: fix linux/if_pppol2tp.h userspace compilation errors

Move inclusion of <linux/l2tp.h> before <linux/in.h>
to fix userspace compilation errors like this:

In file included from /usr/include/linux/l2tp.h:12:0,
                 from /usr/include/linux/if_pppol2tp.h:21,
/usr/include/netinet/in.h:31:8: error: redefinition of 'struct in_addr'

Fixes: 47c3e7783be4 ("net: l2tp: deprecate PPPOL2TP_MSG_* in favour of L2TP_MSG_*")
