[sr-dev] [kamailio] core: fixed passed buffer size in suip2a() (#381)

[topotomaso]

- fix regarding issue #379
- it makes sense to backport this fix to 4.2 and 4.3
- Function suip2a() has never worked properly for IPv6 addresses before.
  The passed buffer size 'sizeof(buf)-4' to ip6tosbuf() was 1 byte to small.
  So ip6tosbuf() has never written any IPv6 ASCII string to the buffer and
  therefor suip2a() always returned an empty IPv6 reference string ("[]").
  Fixed this by changing passed buffer size to IP6_MAX_STR_SIZE.
  For similarity also changed uncritical passed buffer size in call to
  ip4tosbuf() to IP4_MAX_STR_SIZE.
  The function suip2a() is only used by siptrace module when sip_trace()
  script function is explicitly called on sending side e.g. in onsend_route
  block.
