Fix by moving EM_OPENRISC to include/uapi/linux/elf-em.h.

v2: Only move EM_OPENRISC.
Another possible solution for the problem would be to include asm/elf.h
in arch/openrisc/kernel/signal.c. I had actually submitted a patch with
that fix back in August (maybe that is where I remembered the problem from).
Wonder what happened with that patch.
Would it make sense to drop EM_OR32 and replace it with EM_OPENRISC where
it is used ? binutils seems to suggest that EM_OPENRISC is the "official"
definition.
