Ensure that newfs will never create a filesystem with more than 2^32

inodes by cutting back on the number of inodes per cylinder group if
necessary to stay under the limit. For a default (16K block) file
system, this limit begins to take effect for file systems above 32Tb.

This fix is in addition to -r203763 which corrected a problem in the
kernel that treated large inode numbers as negative rather than unsigned.
For a default (16K block) file system, this bug began to show up at a
file system size above about 16Tb.
