project: add MAINTAINERS, github description, and so on about buildkit

[tonistiigi]

This reminds me that there are some more housekeeping files: #19 (comment)

[thaJeztah]

Ah, yes, hadn't come round to doing that

[AkihiroSuda]

also, please set github description?

@thaJeztah @tonistiigi ping 😃

@thaJeztah @tonistiigi We don't need to hurry to add MAINTAINERS and other project files, but could you please set some catchy github description, so that we can get more people interested in this project?

e.g. concurrent, cache-efficient, and Dockerfile-agnostic container image builder (just an example)

[AkihiroSuda]

Also, can we set moby/moby#34227 as the "web site" of this repo, so as to clarify relationship between BuildKit, Moby Core, and Docker?

[tonistiigi]

I updated the description/link.

@thaJeztah Can I assign other files to you. Not urgent as I know you're busy, just want to make sure we are not waiting on each other.
