[klibc] ext3 reported as minix by fstype

In the fstype tool there is a problem if the lower 16 bits of number of free
inodes in a ext3 filesystem happens to match minix filesystem magic since
these fields use the same offset. This will cause an ext3 filesystem to be
reported as a minix filesystem.

I notified the ubuntu people too since they use fstype there to detect the
type of the root filesystem and it seems to be a "common" problem over there.
It renders an ubuntu system unusable until you bump the free inode counter.
