FreeBSD port (39): avoid nscd compilation error

[Bruno Haible]

FreeBSD doesn't have SO_PEERCRED, therefore 'struct ucred' is not defined
in <sys/socket.h>, therefore we get a compilation error in nscd/connections.c:

connections.c: In function `handle_request':
connections.c:394: storage size of `caller' isn't known

The fix is trivial.

	* nscd/connections.c (handle_request): Declare 'caller' inside #if.
