sysctl: remove the binary interface for aio-nr, aio-max-nr, acpi_video_flags



aio-nr, aio-max-nr, acpi_video_flags are unsigned long values which sysctl
does not handle properly with a 64bit kernel and a 32bit user space.

Since no one is likely to be using the binary sysctl values and the ascii
interface still works, this patch just removes support for the binary sysctl
interface from the kernel.
