x86/CET: Update vfork to prevent child return
Child of vfork should either call _exit or one of the exec family of functions. But normally there is nothing to prevent child of vfork from return of the vfork-calling function. Simpilfy x86 vfork when shadow stack is in use to introduce mismatched shadow stack in child of vfork to trigger SIGSEGV when the child returns from the function in which vfork was called.
