x86: Enable unwinding from exception handler

Preserve the .eh_frame section for the linked hypervisor objection and
only remove it from the binary. Then add .cfi directives to the
exception entry code. This enables to use a debugger for unwinding from
the exception handler to the causing function and beyond (not perfect
due to missing stack frames, though).
