    tests: install: Generalize 'run-install'.
    
    * gnu/tests/install.scm (%simple-installation-script): New variable.
    Contains installation script formerly in 'run-install'.
    (run-install): Add 'target-os', 'target-os-source', and #:script
    parameters.  Honor them.
    (qemu-command/writable-image): New procedure.
    (%test-installed-os): Use it.
