UBUNTU: [Debian] hyper-v -- Ensure that hv-kvp-daemon.service starts before walinuxagent.service

BugLink: https://bugs.launchpad.net/bugs/1739107

The hv-kvp-daemon service starts after walinuxagent. The default dependencies make hv-kvp-daemon
wait until the whole system is up before it can start, which is not necessary and blocks Azure
telemetry use case. This commit changes the hv-kvp-daemon.service unit file to start it up as
early as possible so that the channel for telemetry can be use.
