download/grub: delete grub if gnulib cloning fails

for our purposes, grub and gnulib are one in the same

if one fails, both have failed

exit with non-zero status if gnulib fails

the script sets -e so it will fail if grub fails to
download, which is tried before gnulib, and if that
happens, the grub directory is not created
