m4: Replace obsolete AC_HELP_STRING with AS_HELP_STRING.

AS_HELP_STRING is a direct replacement for AC_HELP_STRING.
It is available since autoconf 2.57a.  OVS requires 2.63,
so AS_HELP_STRING can be freely used.

This fixes the following warning on systems with 2.70+:

  $ ./boot.sh
  ...
  configure.ac:92: warning: The macro `AC_HELP_STRING' is obsolete.
  configure.ac:92: You should run autoupdate.
  ...
