Fix race in IOHandlerProcessSTDIO
Summary:
IOHandlerProcessSTDIO::Run() was opening the pipe for interrupt requests lazily. This was racing
with another thread executing IOHandlerProcessSTDIO::Cancel() simultaneously. I fix this by
opening the pipe in the object constructor. The pipe will be automatically closed when the object
is destroyed.
Test Plan: Tests pass on linux.
