Use Gnulib's inet_ntop' and inet_pton' modules.

* m4/gnulib-cache.m4: Add `inet_ntop' and `inet_pton'. * configure.ac: Don't check for `inet_ntop' and `inet_pton'. * libguile/socket.c (scm_inet_pton, scm_inet_ntop): Compile regardless of `HAVE_INET_PTON' and `HAVE_INET_NTOP' respectively. * libguile/filesys.c: Use <stdlib.h> instead of <canonicalize.h>.
