Subject: [PATCH v1 8/9] perf srcline: Add missed addr2line closes

The child_process for addr2line sets in and out to -1 so that pipes
get created. It is the caller's responsibility to close the pipes,
finish_command doesn't do it. Add the missed closes.

Fixes: b3801e791231 ("perf srcline: Simplify addr2line subprocess")
