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.

1This test hangs under 5.0 kernels onwards. It appears to be caused by the commit in the kernel:

7 tcp: implement coalescing on backlog queue

9 In case GRO is not as efficient as it should be or disabled,
10 we might have a user thread trapped in __release_sock() while
11 softirq handler flood packets up to the point we have to drop.
12
13 This patch balances work done from user thread and softirq,
14 to give more chances to __release_sock() to complete its work
15 before new packets are added the the backlog.
16
17 This also helps if we receive many ACK packets, since GRO
18 does not aggregate them.
19
20 This patch brings ~60% throughput increase on a receiver
21 without GRO, but the spectacular gain is really on
22 1000x release_sock() latency reduction I have measured.
