x86/Kconfig: Transmeta Crusoe is CPU family 5, not 6 (2024-02-09 16:28:19 +0100)

----------------------------------------------------------------
- Correct the minimum CPU family for Transmeta Crusoe in Kconfig so that
such hw can boot again

- Do not take into accout XSTATE buffer size info supplied by userspace
when constructing a sigreturn frame

- Switch get_/put_user* to EX_TYPE_UACCESS exception handling when an
MCE is encountered so that it can be properly recovered from instead
of simply panicking
