Subject: [PATCH] socket_SUITE: do not fail on IPv6-only nodes

Before this change, socket_SUITE fails most of IPv4 tests
with IPv4 address available only on loopback adapter. With this
patch:
 - IPv4-specific tests will be skipped on IPv6-only nodes
 - non-specific tests will utilise either v4 or v6, depending
   on availability (with v4 preferred)
 - minor cleanup (removed unused suite/doc functions)
