target/s390x: Fix the "ignored match" case in VSTRS
Currently the emulation of VSTRS recognizes partial matches in presence
of \0 in the haystack, which, according to PoP, is not correct:
If the ZS flag is one and a zero byte was detected
in the second operand, then there can not be a
partial match ...
Add a check for this. While at it, fold a number of explicitly handled
special cases into the generic logic.
