libnm: don't special case "vpn.secrets" property in property_to_dbus()

Browse source 
"nm-setting.c" (and property_to_dbus()) should stay independent of
actualy settings implementations. Instead, the property-info should
control the behavior.

What I like about this change is also that the generic handling is not a
flags "handle_secrets_for_vpn", but it just says to skip checking the
param-spec flags and directly call the to_dbus_fcn(). It's just a
generally useful thing to do, to let the to_dbus_fcn() function also
handle checking the property flags. The fact that only vpn.secrets
properties uses this for a certain pupose, is abstracted in a way that
makes sense.
