anycast_test.py: change to use thread.join to wait CloseFileDescriptorThread finished

The original implementation closes fd in a separate thread,
and the use time.sleep(0.1) to wait it finished, but there is the case that
on platforms like hikey the thread is not finished even after the slept 0.1s,

to make this test works for more platforms, we change to use thread.join(0.5) here
to wait up to 0.5 seconds.

And use thread.isActive to check if there is the hang problem.

Test: run vts-kernel -m VtsKernelNetTest with 4.9 and 4.14 kernel

There will be 1 or more failed in 5 iterations,
after this change all will pass in 10 iterations.
