top: retire old stale startup defaults in favor of new

For over a decade top has used a startup configuration
mimicking the original redhat top. This decision dates
back to when the forked Sourceforge version was trying
to win over users in battles with that ancient kludge.

Will anybody deny that those defaults are coyote ugly?

Well, it is time that top presented a more modern look
at startup, providing that no saved rcfile exists. But
just in case some distro prefers that old, comfortable
look, there's the '--disable-modern-top' build option.

[ Pssst. With the widened memory fields it turns out ]
[ the 'Mem' default window had become almost useless ]
[ on an 80x24 terminal since %CPU & COMMAND were out ]
[ of view. So some other defaults were tweaked a bit ]
[ whether or not --disable-modern-top was specified. ]
