Update Gnulib; add new modules.

This updates Gnulib to v0.0-4889-ge375fe3.

* m4/gnulib-cache.m4: Add `accept', `bind', `close', `connect',
  `getpeername', `getsockname', `getsockopt', `listen', `malloc',
  `malloca', `recv', `recvfrom', `send', `sendto', `setsockopt',
  `shutdown', `socket', and `sockets', requested by
  Jan Nieuwenhuizen <janneke-list@xs4all.nl> for cross-MinGW32 builds.
  Add `trunc', requested by Mark H Weaver <mhw@netris.org>.
