This commit inserts the libefi.a objects in a stable order.

When building libefi.a with "make -jN", the object files in libefi.a
will be inserted in a random order. Although it won't hurt the functionality,
it could make the EFI image irreproducible and invalidate the detached
signature after rebuilding libefi.a without any change in the source
code.
