install-cd: Include nixos-artwork to fix installer tests
With the move from storing grub images in the nixpkgs repo to storing them in the nix store, we broke the installer tests as the iso does not contain the artwork needed for the grub splash. This commit fixes the inclusion of the artwork in the iso.
Should fix at least nixos.tests.installer.simple.x86_64-linux

This solves the problem of e.g. mutt not finding mail unless the user
sets MAIL=/var/spool/mail/$USER.
The default MAIL variable seems come from bash. Reasons for adding
symlink instead of changing MAIL default in bash:
- No need to rebuild world
- FHS recommends /var/mail over /var/spool/mail anyway[1]. Better fix
NixOS mail location than change MAIL in bash to something that doesn't
work on non-NixOS (however unlikely that users run nixpkgs bash on a
non-NixOS distro...).

Commit 159fed47bc (nixos/grub: Fix video display on efi) changed BIOS
systems to start in non-text mode as well. Enable FB_VESA to get a
framebuffer console on BIOS systems. Change FRAMEBUFFER_CONSOLE to 'y'
instead of the default 'm' to so the user doesn't need to manually load
the fbcon module anymore.
Other distros have similar defaults, at least on Arch:
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y
and on Ubuntu (12.04):
CONFIG_FB_VESA=m
CONFIG_FRAMEBUFFER_CONSOLE=y
Fixes#8139
Better replace the double quotes in 'echo "${commands}"' with single
quotes, to prevent the shell from doing command substitution etc. at
configuration build time.
