tests: Use bootstrap and Nixpkgs inputs to be less costly.

* tests/builders.scm (%bootstrap-inputs, %bootstrap-guile): New
  variables.
  ("gnu-build"): Use them, by setting `#:implicit-inputs? #f' and `#:guile'.

* tests/packages.scm (%bootstrap-inputs, %bootstrap-guile): New
  variables.
  ("trivial"): Pass `#:guile %bootstrap-guile'.
  ("GNU Hello"): Use `package-with-explicit-inputs' to use
  %BOOTSTRAP-GUILE and %BOOTSTRAP-INPUTS.
