* gnu/tests/install.scm (%test-installed-syslinux-os): New exported
  variable.

  (%syslinux-gpt-installation-script): New variable.
* gnu/system/install.scm (installation-os)[packages]: Add syslinux.

Hi,

Here's a test installing a GuixSD system with extlinux-bootloader-gpt
as a bootloader.

I had to rewrite %minimal-syslinux-os as a copy of %minimal-os, but the only
change is the bootloader field. A better idea to avoid rewritting is welcome :)

Thanks,

Mathieu
