str-in6addr: bugfix: trailing zero in hex problem.

* stdlib/socket.c (sys:in6addr-condensed-text): The
regular expression used in calculating zr is incorrect;
the zero in it can match the trailing zero of
a nonzero quad, when the intent is only to match
zero quads. Hack: we represent zero quads by the
character Z and use that for the matching and removal
of the longest range of zero quads. Then we filter
the Z back to 0.
