top: modify 'focus' strv function to display 'n/a' too

This commit just brings that 'bot_focus_strv' function
up to the same standard as the vanilla 'bot_focus_str'
guy. Namely, if there is no cmdline or environ for any
process, that bottom window will now display an 'n/a'.

[ with the nature of those string vectors, it wasn't ]
[ the same simple process found for regular strings. ]
