configure.ac: fix a couple more includes on NetBSD (try 3)

[Austin English]

tcp_var has to be included after tcp_timer, which need
netinet/in_systm.h. Also including netinet/in_systm.h for netinet/ip.h
so it doesn't fail.

Try 3:
Moved the order of includes rather than moving tcp_var into it's own
AC_CHECK_HEADER to appease AJ
