bug#26346: [PATCH 12/17] build-system/asdf: Always pre-load the system's definition file.

[Andy Patterson]

* guix/build-system/asdf.scm (asdf-build)[builder]: Pass a default
`#:asd-file' argument to the build procedure, using the system's name.
* guix/build/asdf-build-system.scm (build, check): Adjust to assume that
`asd-file' will always be a string.
* guix/build/lisp-utils.scm (compile-system, system-dependencies)
(test-system): Likewise.
