libsystemd-bus: kernel: add sd_bus_kernel_translate_request_name_flags
Flags used to request a name from kdbus are not identical to what DBus and sd_bus use internally. Introduce a simple function to do the translation for us. It's factored out to a separate function so the dbus-driver instance can make use of it as well.
