Adjust maxfilesize for UFS1 and old 4.4 FFS. For UFS1, increase the limit

to (max block - 1) * bsize.  For DEV_BSIZE, this doubles the limit from
0.5 TB to 1 TB.  For the old 4.4 FFS case, decrease the limit from 0.5 TB
to 2 GB - 1.  Older systems had a 32 bit off_t so they couldn't access the
larger files anyway.
