derivations: Add properties.
* guix/derivations.scm (derivation): Add #:properties parameter. [user+system-env-vars]: Honor it. (derivation-properties): New procedure. (build-expression->derivation): Add #:properties and pass it to 'derivation'. * guix/gexp.scm (gexp->derivation): Likewise. * tests/derivations.scm ("derivation-properties"): New test. * tests/gexp.scm ("gexp->derivation properties"): New test. * doc/guix.texi (Derivations, G-Expressions): Adjust accordingly.
