[PATCH] Remove obsolete, never-implemented XSI STREAMS declarations

My pre-push testing revealed that my previous testing had been
insufficient, and I had to make the changes below.

(Hurd does not have any other GLIBC_2.30 reference, which is why had to
add the section to posix/Versions.)

Does your Reviewed-by: still stand?

Thanks,
Florian
