grub2|loopback: extract install menu entries to config files

backwards compatibility:

 1. the new install.cfg and install_start.cfg files (chosen
    automatically from the install_*gui.cfg and install_*test.cfg
    files) will be included alongside any user custom config.
 2. the placeholders are now replaced with lines importing these files

thus everything will work just as before, i.e. no backwards
compatibility breakage.
