Subject: [PATCH] objtool: make orc_types.h headers match

Building objtool causes a warning on the latest linux-next kernels:

warning: objtool: orc_types.h differs from kernel

>From what I can tell, we have two slightly different copies of the same
header, and we try to ensure they are the same with the warning.

This picks the copy from the x86 headers (without the __packed
annotation), by roll of dice.

Fixes: 39358a033b2e ("objtool, x86: Add facility for asm code to provide unwind hints")
Fixes: 627fce14809b ("objtool: Add ORC unwind table generation")
