sessions: oops, we made up a function

Turns out that in commit 6bd36a7 we had a function that is not part of the MPI standard.
This showed while working on ABI support - which requires us to pay attention to the truth
rather than make stuff up.

This commit removes our made up MPI_Session_set_info method.
Turns out who ever was doing the fortran bindings knew this wasn't a method in the standard
so there's no need to change the fortran bindings.  Same thing applies to the man pages.
