Subject: network: log when no matching .network file found
X-Git-Tag: v257-rc1~416^2~4

network: log when no matching .network file found

When an interface enters unmanaged state, there are two possibilities:
- no matching .network file found,
- found a matching .network with Unmanaged=yes.

When a matching .network file is found, networkd logs the filename.
Let's also log when no matching .network file is found.

This also slightly adjust the log message when a matching .network file
found.

Closes #34436.
