[bug#32582] [PATCH 4/5] build-system/asdf: Adopt asdf conventions.

[Andy Patterson <ajpatter@uwaterloo.ca>]

The asdf documentation specifies that asdf:load-asd should be preferred to
calling load on a system definition file.

* guix/build/lisp-utils.scm (compile-system): Replace load with asdf:load-asd.
(system-dependencies): Likewise.
(test-system): Likewise.
