    Call sv_onexec hook after the process VA is created.
    
    For future use in the Linux emulation layer call sv_onexec hook right after
    the new process address space is created. It's safe, as sv_onexec used only
    by Linux abi and linux_on_exec() does not depend on a state of process VA.
