Alexander Graf 52a250afa5 efi_loader: helloworld.c: Reduce file size
The efi linker script includes sections needed for the dynamic linker.
However, in our EFI application environment we don't have a dynamic linker.

So let's remove them. That way we save on 4k padding and reduce the file
size of the hello world efi binary from ~4k to ~1k.
