Move sysmocom-openvpn-config task-sysmocom-tools -> feed

Package sysmocom-openvpn-config was recently added to
task-sysmocom-tools. That task is pulled in by default into images. We
don't actually want that. Instead, we want the package to be available
in feeds, but without being installed into the image by default. Hence,
revert the recent commit and put the package in task-sysmocom-feed.bb
instead.
