Allow poll to wait for a signal on the socket instead of requiring that
it be set immediately. This fixes flakiness caused by connections not
being established fast enough. For https://fxbug.dev/124433

Before this change, this test fixture expected it to be enabled already
instead of updating the config.
The Teardown method also restore the initial configuration, so that
these tests do not permanently change the config of the machines that
run the tests.

NewTempAbsPathInDir("/tmp") prevents the generated socket address from
exceeding sizeof(addr.sun_path). However, existing systems that are built with
the ANDROID configuration have their temp directory in a different location.
This change allows those systems to run tests that depend on UniqueUnixAddr.
