build: add Dockerfile to build C# node from sources

Add ability to build the following services from sources:
- neo
- neo-vm
- neo-cli
- neo plugins

Important: it's up to you to keep an eye on services versions matching.
This dockerfile just replaces specified .dlls with the built one, so be
careful while setting CLIBRANCH, MODULESBRANCH, NEOVMBRANCH and NEOBRANCH
env variables.
