[secureboot] Add secureboot support for Arista devices (sonic-net#4741)

* Add secureboot support in boot0 * Initramfs changes for secureboot on Aboot devices * Do not compress squashfs and gz in fs.zip It doesn't make much sense to do so since these files are already compressed. Also not compressing the squashfs has the advantage of making it mountable via a loop device. * Add loopoffset parameter to initramfs-tools
