sshpeer: store subprocess so it cleans up correctly

When running 'hg pull --rebase', I was seeing this exception 100% of the
time as the python process was closing down:

Exception TypeError: TypeError("'NoneType' object is not callable",) in
<bound method Popen.__del__ of <subprocess.Popen object at 0x937c10>> ignored

By storing the subprocess on the sshpeer, the subprocess seems to clean up
correctly, and I no longer see the exception. I have no idea why this actually
works, but I get a 0% repro if I store the subprocess in self.subprocess,
and a 100% repro if I store None in self.subprocess.

Possibly related to issue 2240.
