kea-ctrl-agent does not start because of empty capabilities (Alpine v3.18.2)

The kea-ctrl-agent init.d conf has the capabilities variable, but without any content.

The absence of content is because of https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/main/kea/APKBUILD#L262.

Problem is, when the variable is empty, I get the following error: "Could not parse iab: Invalid argument".

If I remove the capabilities variable from /etc/init.d/kea-ctrl-agent or if I put it some content (for instance, capabilities="^cap_net_bind_service"), the service starts correctly.

This is probably since cbcfa064
