gexp: Add #:target parameter to 'gexp->derivation'.
* guix/gexp.scm (lower-inputs): Add #:system and #:target. Use 'package->cross-derivation' when TARGET is true. Honor SYSTEM. (gexp->derivation): Add #:target argument. Pass SYSTEM and TARGET to 'lower-inputs' and 'gexp->sexp'. (gexp->sexp): Add #:system and #:target. Pass them in recursive call and to 'package-file'. * tests/gexp.scm (gexp->sexp*): Add 'system' and 'target' parameters. ("gexp->derivation, cross-compilation"): New test.
