move grub-pc specific code to actual grub-pc script

the grub-pc image creation code has no business being in binary_iso, it
should be in binary_grub-pc.

it should be noted that the binary_iso script did not even have the
necessary package check for grub-mkimage, while binary_grub-pc did have
it, pointlessly.
