Fix overwritten zone string

Browse source 
* time.c (zone_str): while rb_fstring_usascii and the family
  require that the argument string is never modified, tzname may
  point areas which will be discarded by calling tzset().
  make a String then call rb_fstring to copy the zone name.
  when an ID equals TZ environment variable, its name string also
  has modified by changing tzname.
