Updated ogg.m4 using autoupdate to avoid warnings from autoconf.

This got rid of these messages from autoconf when using XIPH_PATH_OGG
from ogg.m4:

  configure.ac:5: warning: The macro `AC_HELP_STRING' is obsolete.
  configure.ac:5: You should run autoupdate.
  ./lib/autoconf/general.m4:204: AC_HELP_STRING is expanded from...

  configure.ac:5: the top level
