Update installation to be more fine-grained

Install different prerequisites and tagged version of the amazon/efs-utils
package depending on the host. This will allow hosts that support the
Rust toolchain v1.65+ to use efs-utils v2 while hosts with an older
version of the Rust toolchain are held back on the last v1 release.
