[PATCH] ntdll: Remove a special case for EP not in executable section in map_image_into_view().

    It is a very old hack and testing shows that there is no special case on Windows for entry
    point being inside the section without execute flag. My guess is that maybe this
    was introduced before 'force_exec_prot' (NtSetInformationProcess(ProcessExecuteFlags) or
    IMAGE_DLLCHARACTERISTICS_NX_COMPAT were properly supported.
