Bug#581049: grub-pc: Use desktop-grub alternative in 05_debian_theme

[Jeremy Lal]

Package: grub-pc
Version: 1.98-1
Severity: wishlist

Replacing the hard-coded WALLPAPER in 05_debian_theme is quite easy,
WALLPAPER=$(readlink -f /usr/share/images/desktop-base/desktop-grub)

However grub's postinst and prerm should install alternative,
if that's not already the case.

Cheers,
Jérémy.
