Door lock script updates hard code the endpoint to 1

[cecille]

This needs to be taken from the endpoint argument to the script or this test will fail every device that doesn't implement the door lock with this exact endpoint composition.

Some of the old test cases are using --int-arg endpoint: 1 for setting endpoints. For recently implemented python scripts like DRLK_2_13 python script we can change the script to use --endpoint 1
