Subject: [PATCH] ftracetest: replace usleep by sleep

'usleep' seems to be a distro-specific utility and may not be
available:

 [5] event tracing - enable/disable with event level files       [FAIL]
 execute: /home/miguel/linux/tools/testing/selftests/ftrace/test.d/event/event-enable.tc
 + . /home/miguel/linux/tools/testing/selftests/ftrace/test.d/event/event-enable.tc
 + [ ! -f set_event -o ! -d events/sched ]
 + reset_tracer
 + echo nop
 + do_reset
 + echo
 + clear_trace
 + echo
 + echo sched:sched_switch
 + usleep 1
 ./ftracetest: 24: /home/miguel/linux/tools/testing/selftests/ftrace/test.d/event/event-enable.tc: usleep: not found

Replace it with the more standard sleep.
