Telemetry: use print instead of logging

Using the logging library before UTR can set it up puts it in a weird
state that consumes all output. Instead of using logging, just print
anything from initializing telemetry.

Also make some small updated to avoid features not supported by
non-linux os's right now (these have been generating unnecessary
warnings)
