autogen: Copy automake tools

Building the dist tarball in the current Fedora 37 cockpit/tasks
container now fails when running as user podman container, when using
systemd-homed:

    cp: failed to preserve ownership for 'cockpit-279.39.gb4b41375f/tools/compile': Value too large for defined data type

This was due to a change in systemd 251 with mapped user IDs[1][2].

Work around this by copying the files instead of symlinking them. That
is the default behaviour anyway, and does not hurt much: git trees are
regularly cleaned by developers anyway, and dist tarballs contain a copy
either way.
