profiles: simplify profiles to suites
* Leave importing to nixpkgs module implentation. Provide a path
  instead; resolves #136.
* Allow profiles which are not lambdas but simple attribute sets,
  relaxing the constraints a bit.
* Update profile README.md
* defaultImports -> mkProfileAttrs: allow importing subprofiles even
  if parent directory does not contain a default.nix.
