Fix my yesterday's brain-o: don't account for the kilobytes twice.

Yikes! Originally, i intended to apply the patch from PR # 1322,

but Bill has beaten me on this. ;-) However, he missed the part to compute the kernelsize in kilobytes, so the minfree consideration was now overcautious. (I've also changed the return type of dump_size() to void since int was useless.) Being here, the fact that `vmcore' was written world-readable was just a plain security hole: everybody who was able to crash a kernel could later read any confidential information out of it at his will. Create it with umask 077 instead.

Make the savecore command work like the man page says:

- make minfree work by getting the dump size before checking to see if the dump will fit on the filesystem - also fail to dump if no minfree is specified but there are not enough free blocks. Fix a typo in the man page. Fixes PR bin/1322 Submitted by: "Philippe C."
