python3: Avoid hanging tests

There are python tests which hang with recent kernels, 5.0 onwards. This causes
ptest to timeout for python3. Disable the problematic test until we better understand
the real cause and fix of the issue (discussions are happening with upstream).

See the patch for details/links.
