treewide: implement basic aarch64 support
This adds aarch64 platforms, and some fixes for aarch64 support. This is
not yet complete; e.g. toolchains for aarch64 targets are still missing.
I renamed the amd64 platforms to x86_64 and efi to uefi for consistency
with @platforms.
syscall.Dup2 does not exist on arm64, but unix.Dup2 does.
