libbb/sha1: in unrolled x86-64 code, pass initial W[] in registers, not on stack
...
This can be faster on some CPUs.
On Skylake, evidently load latency from L1 (or store-to-load
forwarding in LSU) is fast enough to completely hide
memory reference latencies here.

mkfs.vfat: fix volume label to be padded with space

The specification requires volume label to be space padded.
Latest fsck.vfat will remove the zero padded volume label
as invalid. See also:
https://github.com/dosfstools/dosfstools/issues/172
Make the default label also "NO NAME" which has the special meaning
that label is not set.
