move this file to Attic; the swapon(2) system call cannot be accessed

from userland since April 2003 and, of course, the manual page is
not built either.

see miod@'s change in r1.66 of src/lib/libc/sys/Makefile.inc.

i would like to acknowledge the excellent advice from jmc@ and
fgsch@ with relation to this change.

ok miod@
