Convert the maxusers directive to a normal MAXUSERS option (normally

define MAXUSERS in opt_param.h as directed in /sys/conf/options;
if it's not mentioned there, then define it in IDENT; never define
it in PARAM).  MAXUSERS probably should be a completely normal option.

Don't define PARAM now that it is empty.

Cleaned up similar conversion of cpu directives to XXX_CPU options.
