Josh Poimboeuf 4873939c0e x86/srso: Fix return thunks in generated code ...

Upstream commit: 238ec850b95a02dcdff3edc86781aa913549282f

Set X86_FEATURE_RETHUNK when enabling the SRSO mitigation so that
generated code (e.g., ftrace, static call, eBPF) generates "jmp
__x86_return_thunk" instead of RET.

  [ bp: Add a comment. ]
