when setting force tlsPolicy for dfdaemon, something still connect download unix sock with non-TLS

[karlhjm]

Bug report:

I haven't taken any download action at this time but something is accessing the download unix sock through non-TLS, whie I set tlsPolicy to 'force'

Expected behavior:

when setting force tlsPolicy, every client access download unix sock with tls

How to reproduce it:

here is the main config of dfdaemon, use tlsPolicy: force and tlsVerify

[karlhjm]

the command of dfdaemon is "/opt/dragonfly/bin/dfget daemon --v=10"

[jim3ma]

The dfget daemon does not write these log, you can find which process writes the logs file.
