This change adds socket system call hooks to existing test cases for
simulating a bit complicated network conditions to help making timeout
and dual IP stack test cases work more properly in followup changes.
Also test cases print debugging information in non-short mode like the
following:
Leaked goroutines:
net.TestWriteTimeout.func2(0xc20802a5a0, 0xc20801d000, 0x1000, 0x1000, 0xc2081d2ae0)

Having this test fail, as it does reliably for me,
makes working frustrating. Disable it for now,
until we can diagnose the issue.
Update issue #8859.

The change 2096 removed unwanted allocations and a few noises in test
using AllocsPerRun. Now it's safe to enable this canary test on netpoll
hotpaths.
