Supersed killbig-nits

Fix print calls in swap.c^page and proc.c^killbig so they make sense and are in a more
logical order.

Change killbig to not have hardcoded the file server name and instead avoid killing
process owned by eve that have non-writeable /ctl.

Still not sure exactly where in the rc scripts this line would fit best:
for(i in `{ps|grep '(kfs|fossil|venti)'|awk '{print $2}'}) { chmod -w /proc/$i/ctl; }
