x86/process: Re-export start_thread()
The consolidation of the start_thread() functions removed the export
unintentionally. This breaks binfmt handlers built as a module.
Add it back.
Fixes: e634d8fc792c ("x86-64: merge the standard and compat start_thread()
functions")

What for? Perhaps 32-bit could remove it instead?
Came across this while writing a binfmt module. Useful for me but
probably no one else on Earth, at least for another ~9 years on average.
