Kernel+LibC: Don't allow a directory to become a subdirectory of itself
If you try to do this (e.g "mv directory directory"), sys$rename() will
now fail with EDIRINTOSELF.
Dr. POSIX says we should return EINVAL for this, but a custom error
code allows us to print a much more helpful error message when this
problem occurs. :^)
