uclient: Update statfs to match the kernel client and its block sizing.

Make it better match the kernel client, and its scheme to use a large
block size so we don't overflow 32-bit systems. This isn't presently
a serious concern since FUSE doesn't work on 32-bit systems anyway,
but the output of df should match even so.
