doc: ffi: clarify in and out nuances.
* txr.1: Fix wrong wording about the by-value nuance of the in operation. What is specifically doesn't do, in contrast to the by-pointer nuance, is propagate the foreign representation back to Lisp. Not Lisp to foreign, which is opposite to the in operation. Also clarifying some wording in the description of the out operation: that the by-value nuance doesn't reconstruct from the updated Lisp structure, to help the reader keep in mind the data direction.
