[bug#36578] [PATCH 1/9] derivations: 'derivation' primitive accepts <derivation> and #:sources.

[Ludovic Courtès]

This brings us closer to the <derivation> data type.

* guix/derivations.scm (derivation): Add #:sources parameter.
[input->derivation-input]: Add clause for 'derivation-input?'.
Honor SOURCES.
