[test] rename SegwitVersion1SignatureHash()

The function implementing segwit v0 signature hash was originally named
SegwitVersion1SignatureHash() (presumably before segwit v0 was named
segwit v0). Rename it to SegwitV0SignatureHash().

Also rename SignatureHash() to LegacySignatureHash() for disambiguation.
