libqmi-glib,udev: change qmi_wwan sysfs attr ownership to QMI_USERNAME if set
If the build system has defined a username to change the ownership of
the QMI control device, use the same username to change ownership of
the sysfs attributes exposed by the qmi_wwan driver, which allow us to
control e.g. raw-ip vs 802.3 link layer protocol management or
multiplexing support features.
