tests: fix tests for 1a211cb (missing well-known)

Fix tests/aspathtest.c again, this time by including a NEXT_HOP
attribute (which is out of correct order with AS_PATH, but that doesn't
matter here.)  This satisfies bgp_attr_check(), which after 1a211cb
refuses updates without nexthop attribute.

Fixes: 1a211cb ("one more fix for tightening of check for missing well-known attributes")
