gnulib-tool change for Autoconf 2.60 and onceonly

[Paul Eggert]

While bootstrapping Bison I noticed that gnulib-tool assumes Autoconf
versions 2.57 through 2.59.  But Bison assumes 2.60.  On the theory
that gnulib-tool should assume the latest stable version, and you
can copy onceonly by hand if you want an earlier one, I installed
this:

        * gnulib-tool (func_get_filelist): Don't echo m4/onceonly_2_57.m4,
        for the benefit of people using Autoconf 2.60.  If you want to
        support older Autoconf versions you can copy m4/onceonly_2_57.m4
        (or m4/onceonly.m4, if pre-2.57) manually.
