Colin Walters 80fd2e883b README.md: Add a "why" section, update background.md
Point at FCOS and not Project Atomic.  Add an inline "Why"
section since people will want to know that right away.

(An great thing about Github is the prevalence it gives to `README.md`;
 projects should use that as an "elevator pitch")

Drop outdated bits in `background.md`.
