r24147 (ticket #6746) made libgssrpc ignorant of the remote address of
the kadmin socket, even when it's IPv4.  This made old-style GSSAPI
authentication fail because it uses the wrong channel bindings.  Fix
this problem by making clnttcp_create() get the remote address from
the socket using getpeername() if the caller doesn't provide it and
it's an IPv4 address.
