util/grub-install: Allow recursive copying of theme dirs

Browse Source 
grub-install allows to pass a parameter to install a theme in the boot partition.
This works fine for the default starfield theme. However, in general themes can
contain subdirectories, as, e.g. "icons", and these are not copied by grub-install.
As a result, the icons are missing on the screen.

Fix this by simple recursive copying.
