drop neighbor_ident_test.c

This tests the opaquely designed neighbor config storage. However, a
subsequent patch will refactor the neighbor config storage, and this
neighbor ident API will change fundamentally. No need to test this.

The new storage will use the usual scheme of transparent struct and
llist, the opaque design is not necessary and just bloats. There is no
need to test a plain llist, so this test needs no replacement.
