README: drop reference to old ABI /sys/kernel/debug/sched/ext

We have moved generic sched-ext status files outside of debugfs, so that kernels without SCHED_DEBUG enabled can also access this information. However, the README.md file is still showing the old ABI in an example. Replace it with the new sysfs interface to avoid confusion. Signed-off-by: Andrea Righi <andrea.righi@canonical.com>
