top: remove those winflags which restricted 'x' toggle <=== port of newlib ef8d1cb6

______________________________ original newlib message

On occasion, even as the top author, I wonder why that
'x' toggle has stopped working. Of course, it actually
was working but a locate request ('L') or other filter
('O') operation was active and thus temporarily turned
if off. Such behavior is documented in top's man page.

Well, with this patch that 'x' suppression is no more.

[ the original justification, however, remains true. ]

[ but there's really only one character which causes ]
[ any potential trouble & i'm gonna' keep it secret. ]

[ besides, if a display is corrupted, there's always ]
[ that '=' key which restores things back to normal. ]
