Subject: [PATCH v2] telemetry: fix "in-memory" process socket conflicts

When DPDK is run with --in-memory mode, multiple processes can run
simultaneously using the same runtime dir. This leads to each process
removing another process' telemetry socket as it started up, giving
unexpected behaviour.

This patch changes that behaviour to first check if the existing socket is active.
If not, it's an old socket to be cleaned up and can be removed. If it is active,
telemetry initialization fails and an error message is printed out giving
instructions on how to remove the error; either by using file-prefix to have a
different runtime dir (and therefore socket path) or by disabling telemetry if it
not needed.

Fixes: 6dd571fd07c3 ("telemetry: introduce new functionality")
