Add the ability to transform Grub program names. For example, a user can easily launch

./configure --program-transform-name="s/grub/grub2/"

And the installed files (in this case for i386-pc) will be:

/usr/lib/grub2/i386-pc/*
/usr/local/sbin/grub2-emu
/usr/local/sbin/grub2-install
...etc

Also grub2-install place boot files in "/boot/grub2"

This allows easy integration into distributions as it allows grub2 to
sit side by side with a grub legacy install without.
