x86/sev: Move the instrumentation exclusion bits too

Commit in fixes moved the sev*.c compilation units to coco/ - the guest
confidential computing location - where they belong but forgot the
instrumentation exclusion build directives.

Move them too.

Fixes: 06685975c209 ("x86/sev: Move SEV compilation units")
Closes: https://lore.kernel.org/oe-kbuild-all/202406220748.hG3qlmDx-lkp@xxxxxxxxx
