crypto: LLVMLinux: aligned-attribute.patch

__attribute__((aligned)) applies the default alignment for the largest scalar
type for the target ABI. gcc allows it to be applied inline to a defined type.
Clang only allows it to be applied to a type definition (PR11071).

Making it into 2 lines makes it more readable and works with both compilers.
