fdlength: device size is reported in bytes, not blocks.

The shift was a remnant from when BLKGETSIZE (which measures in
blocks) was being used on Linux. The Mac has two separate ioctls
for block count and block size, which we're already multiplying
together. And on Linux we're using BLKGETSIZE64, which returns a
result in bytes, not blocks. So lose the shift.
