Adds: 1. grub-efi package mappings 2. efi-64 support 3. default (openrc) arm64 profile 4. systemd arm64 profile Cleans up the keywords and use flags in 02-gentoo-02-flags. Most stuff was stablized. Also cleaned up some formatting for the if statements. Enables less trusted overlays (up to the end user to verify). in 10-gentoo-image I cleaned up some bash lint things as well. using && instead of -a and avoiding $?
