We need to somehow isolate the git configuration being used to build GNU Boot from the rest of the system as otherwise things like automatic gpg signatures can kick in and block the build because it waits for a pinentry. In addition: - It enables us to simplify the build code as the git configuration is now the same during all the build. - Contributors don't need to setup git anymore just to build GNU Boot. This also makes GNU Boot a bit more reproductible. Replacing git inside the build scripts / Makefiles enable us to still run them manually (like ./resources/packages/coreboot/download).
