description:
Convert MAXUSERS, take 2.

Define MAXUSERS in opt_param.h and include it from sys/param.h, for more
accurate dependency.  Don't define -DMAXUSERS and add it to ${CPPFLAGS}.
config(5)'s "maxusers" syntax doesn't change.

(The version just before revert was OK, but I had something bad in my obj
dirs.)
