linux_backdoor.S is missing

[victortan1972]

backdoor_client.py requires linux_backdoor.S to inject the backdoor code to Linux side.

However, linux_backdoor.S is missing now, so please upload it for a good demo.

Hi @victortan1972

The objective of this proof of concept is to demonstrate the design issue in the harware communication channel. We choose not to release a fully functionnal backdoor code.
