Andrew Cooper 7b9814b250 x86/spec-ctrl: Cease using thunk=lfence on AMD ...

AMD have updated their Spectre v2 guidance, and lfence/jmp is no longer
considered safe.  AMD are recommending using retpoline everywhere.

Update the default heuristics to never select THUNK_LFENCE.

This is part of XSA-398 / CVE-2021-26401.
