Hi,
I noticed that wg syncconf does not actually clear PresharedKey and
PersistentKeepalive values if those are not set in the file but set in
the running config. The proposed patch changes that to always
clear those if they are not set in the configuration file, which imho is
the correct behavior.

make wg syncconf correctly clear a preshared key or keepalive in case
the file config does not define those; currently syncconf does not
change these settings at all if runtime has them set but file does not
