top: relocate a prototype to prevent compiler warning

Until the 'locate/search' provisions were added,
top avoided the need for any function prototypes
through careful source file organization.  But
the addition of the find_string function required
a prototpe for task_show, lest a massive file
reorganization be undertaken.

This commit moves the actual protype out of top.h
and places it adjacent to the caller in order to
avoid a warning when top_nls.c is compiled.
