x86/entry/64: Use ENTRY() instead of ALIGN+GLOBAL for stub32_clone()

ALIGN+GLOBAL is effectively what ENTRY() does, so use ENTRY() which is
dedicated for exactly this purpose -- global functions.

Note that stub32_clone() is a C-like leaf function -- it has a standard
call frame -- it only switches one argument and continues by jumping
into C. Since each ENTRY() should be balanced by some END*() marker, we
add a corresponding ENDPROC() to stub32_clone() too.

Besides that, x86's custom GLOBAL macro is going to die very soon.
