So the solutions AFAICS are:

1. Have systemd-sysctl lose the ConditionPathIsReadWrite, and
systemd-sysctl itself should check which prefixes are writable.
2. Have lxc (or the template) ship a new systemd-sysctl-net.service,
that includes the new ExecStart and an updated
ConditionPathIsReadWrite

Option 2 looks like something that has a chance of being fixed in
jessie, although by the LXC folks. Option 1 may be addressed upstream,
but I don't think this fits backporting material.
