Derek McGowan fcdaa2d6b3 Atomically save libtrust key file ...

The libtrust keyfile which is used to set the "ID" property of a daemon must be generated or loaded on every startup.
If the process crashes during startup this could cause the file to be incomplete causing future startup errors.
Ensure that the file is written atomically to ensure the file is never in an incomplete state.

Fixes #23985
