x86/retpoline: Avoid retpolines for built-in __init functions

commit 66f793099a636862a71c59d4a6ba91387b155e0c upstream.

There's no point in building init code with retpolines, since it runs before
any potentially hostile userspace does. And before the retpoline is actually
ALTERNATIVEd into place, for much of it.
