    image.bbclass: delete DATE variable too
    
    When creating a custom image which uses the DATE variable the basehash
    seems to change every day and lead to errors such as:
    ERROR: console-tdx-image-2.7.6-r0 do_image_customimg: Error executing a python function in 
exec_python_func() autogenerated:
    
    The stack trace of python calls that resulted in this exception/failure was:
    File: 'exec_python_func() autogenerated', lineno: 2, function: <module>
         0001:
     *** 0002:set_image_size(d)
    ...
    
    Add DATE to the variables which should not get expanded early and to the
    vardepsexclude list for the image task.
