autoconf-archive: manually patch C++20 support

autoconf-archive added support for C++20 finally in v2022.02.11
but none of the Ubuntu distro versions have picked this up
yet (checked impish and jammy).  Manually patch the file so that
we can upgrade our autoconf-based C++ repositories to use C++20.

The v2022.02.11 version is already included in Yocto.
