top: remove residual logic for obsolete functionality

At one time the 'open_psdb_message' library call was
supported with the concept of a postponed message
which would display after top startup completed.
In turn, that required logic to strip the '\n' which
was embedded (inappropriately) in any such message.

Nowdays top treats such a returned error as fatal so
there is no need for the 'strim' function which is
being removed with this commit.
