x86_64: remove kernel image post-build ELF32 patch
...
this patch must now be done by the wider OS build system, to avoid
interference with any bootloaders that don't support this kind of
patching (e.g GRUB i386-pc)

handle: re-arrange handle space layout
...
the lowest 2 bits of handle values are no longer unused, and 0 is
now a valid handle value.
the first 64 handles are now reserved, and will not be automatically
allocated by the kernel. however, they are still valid handles, and
other handles can be moved to this area using an as-yet-unwritten
function. this is to allow support for standard POSIX file descriptors,
which require the values 0, 1, and 2.
