python3: Drop ptest hack

Browse Source 
With the kernel TCP backlog queue coalescing bug fixed in the 5.0 kernels
we don't need this patch anymore and can run the tests.

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

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