Disable flaky java11 tests.

Browse Source 
Regarding ThreadCpuTimeArray.java: The test starts 10 threads, each of which
does some computation, then blocks. When all threads are blocked, the test
sleeps for 200ms, then checks that less than 100ns of CPU time in userspace
elapse over the course of the sleep; AFAICT, the 100ns of slop is because a
thread indicates that it's in the WAITING state before it actually blocks, and
because signals can cause threads to be temporarily woken. gVisor's CPU clocks
have a granularity of 10ms (the interval of Kernel.cpuClockTicker is
//pkg/abi/linux.ClockTick), so a single tick pushes the test over the
threshold.
