top: treat all of those vertical scroll keys uniformly

Browse Source 
When not displaying all tasks (the 'i' toggle is off),
the concept of vertical scrolling has no real meaning.

However, only 2 keys (up/down) impacting that vertical
position were currently being disabled with this mode.

This patch will extend such treatment to the following
additional vertical impact keys: pgup,pgdn,home & end.
