src: add built-in ogrelive grub2 boot mode templateHEADv1.2.5-26master

Add built-in ogrelive grub2 boot mode template and use it to generate the grub2
boot file for each computer for the new live system.

Use grub2 http to download vmlinuz, initrd.img.

Use live support to download filesystem.squashfs through http.

check for vmlinuz in cache, as usual, otherwise fallback to network boot.
