packages/quilt: Fix build of quilt 0.45
    The aclocal.m4 is an automatically generated file, created by aclocal.m4.
    The OpenEmbedded project automatially removes this automatically generated
    file to regenerate it using aclocal.
    Readd the content from aclocal.m4 as acinclude.m4 which will be seen by
    the same set of programs...
    Or as the automake website says:
        "The contents of `acinclude.m4', if it exists, are also automatically included in
`aclocal.m4'. This is useful for incorporating local macros into `configure'."
