Our NSS version is closer to the currently-released .1, so bump version
to that.
Note: we still have some additional patches to the in-tree version in
place so this isn't a 100% match to the RTM one.
SFTKSession objects are only ever actually destroyed at PK11 session
closure, as the session is always the final holder -- and asserting
refCount == 1 shows that to be true. Because of that, NSC_CloseSession
can just call `sftk_DestroySession` directly and leave
`sftk_FreeSession` as a no-op to be removed in the future.
