Ian Wienand 7b4c8abce3 Choose appropriate bootloader for block-device

In the prior change we added block-device-[mbr|gpt|efi] elements to
create appropriate disk-layouts.

This adds an environment flag to each so the bootloader can install
the right thing.  The EFI install path is updated to work with this
(this part a copy of I572937945adbb5adaa5cb09200752e323c2c9531)

We do some basic sanity checking in the block-device elements;
e.g. mbr is not suitable for aarch64, and efi is not suitable for
power.

This updates the bootloader to install EFI where appropriate

bootloader

Installs grub[2] on boot partition on the system. In case GRUB2 is not available in the system, a fallback to Extlinux will happen. It's also possible to enforce the use of Extlinux by exporting a DIB_EXTLINUX variable to the environment.

Arguments

DIB_GRUB_TIMEOUT sets the grub menu timeout. It defaults to 5 seconds. Set this to 0 (no timeout) for fast boot times.
DIB_BOOTLOADER_DEFAULT_CMDLINE sets the CMDLINE parameters that are appended to the grub.cfg configuration. It defaults to 'nofb nomodeset vga=normal'
