[goldfish] Synchronize pipe ID when creating new pipes.

Pipe ID needs to be locked when creating new goldfish Pipes,
otherwise there can be data races on that ID variable which cause
flakiness in our tests.

TEST=Add a new test case PipeDeviceTest.CreatePipeMultiThreading
     where two threads keep creating pipes and we check IDs of
     pipes created.
