ovn: fix missing scripts and wrong paths

Add missing ovs-appctl and ovs-vsctl scripts used by ovn-ctl.

ovs-ctl is looking for ${bindir}/ovs-appctl but I did not find a configure flag for bindir and sbindir in OVS, which default to /usr/local/{bin,sbin}, so I fixed it with sed.

We need to set the --with-dbdir configure flag so that ovn_dbdir does not default to ${ pkgs.ovn }/etc/ovn and is not in the Nix store, as ovn_dbdir contains stateful information.

"--enable-ssl" is the default if I did not misread the autoconf files, but it does not hurt to add it.

pkgs/by-name/ov/ovn/package.nix
