examples/l3fwd-power: fix telemetry command registration

Telemetry command registration fails if the command name contains
characters other than alphanumeric, underscore (_), and forward
slash (/).

The l3fwd-power example previously used "/l3fwd-power/stats"
as telemetry command, which includes a hyphen (-) and causes
registration failure.

This patch fixes the issue by replacing the hyphen with an
underscore, changing the command to "/l3fwd_power/stats"
