traced_probes: capture stderr from atrace This changes adds the plumbing to capture the output of atrace's stderr. It does this by creating a pipe, changing the fd of atrace's stderr to point to this pipe and then reading the data from this pipe on the parent process. Currently, nothing is done with this data but we will eventually define an error packet and surface this info in the trace. Bug: 118760951 Change-Id: I41196ed468d70440a76f59ad08382f2079e66ce9
