tests: increase CPU percentage threshold for assert_cpu_usage_low
When sleeping for the tick rate of 100ms (defined in
thread_pthread.c) as we do in test/ruby/test_io.rb
(test_copy_stream_no_busy_wait), it may not be possible to
measure with <= 10ms resolution on 100HZ systems (CONFIG_HZ in
the Linux kernel). So increase the threshold to 15ms (10ms +
5ms slack for slow systems).
* test/lib/test/unit/assertions.rb (assert_cpu_usage_low):
increase pct default value [ruby-core:81427]
