selftests: vDSO: don't include generated headers for chacha test

It's not correct to use $(top_srcdir) for generated header files, for
builds that are done out of tree via O=, and $(objtree) isn't valid in
the selftests context. Instead, just obviate the need for these
generated header files by defining empty stubs in tools/include, which
is the same thing that's done for rwlock.h.
