add uaccess tag to devices
udev automatically gives the user in the active
session permissions on all devices with the
uaccess tag (see also 70-uaccess.rules). This
means that it not necessary anymore to be
in the adbusers group if the user is in an active
session (which should pretty much cover 99% of
all use cases).
