waf: ardupilotwaf: rename build_shortcut() to build_command()

Rationale:
 1. That function creates a separate build context class instead of just
    creating a wrapper for calling build (previous approach).
 2. The check command isn't a build shortcut since there's no way of calling it
    without using 'check' explicitly.
