datapath: Do not log when kernel config not found
datapath: Do not log when kernel config not found

Previously, when cilium-agent couldn't find a kernel config (a case for
distros which do not expose the config via /proc/config.gz, but instead
they store it in /boot, which is not mounted into a cilium container),
we logged the following message:

level=info msg="BPF system config check: NOT OK." error="Kernel Config
file not found" subsys=linux-datapath

This confused users making them to think that the missing kernel config
was to blame for their connectivity issues. Thus, this commit silences
the message (missing CONFIG_BPF would anyway result in non-cryptic error
message).

We can bring the message back once
https://github.com/cilium/cilium/issues/14314 has been resolved.
