Docker version of Dontbug

[sidkshatriya]

It might be a good idea to provide some sort of docker version of Dontbug.

Its not going to be practical in most cases to run Dontbug within Docker (as it requires --privileged mode) (See rr-debugger/rr#1784 ). So as a substitute, Dontbug can be built within Docker and then the build can be copied over into the host perhaps.

@sidkshatriya that's a good idea currently I'm also searching for a docker image of Dontbug still I couldn't find any
