Adding Dockerfile

[prince-chrismc]

This is primarily to help support Vuls #3

Fixes #3

What I have tested:

1. ran docker image build
2. ran docker run --rm -it -v $PWD:/vuls -v $PWD/go-exploitdb-log:/var/log/vuls vuls/go-exploitdb:test fetch
3. ran docker run --rm -it -v $PWD:/vuls -v $PWD/go-exploitdb-log:/var/log/vuls vuls/go-exploitdb:test fetch -deep
4. also performed a vuls scan && report which produced the same results as a manual installation

What I would like to add:

• Adding Dockerfile to build image
• Mentioning contributors
• Fixed typo in README

What is left to do:

• [x] Validate Dockerfile, was not sure what to point for maintainers
