configsession: T3259: avoid deadlock when data fills stdout pipe
If the subprocess is producing enough data (in this case showConfig on a
large config file), then the construction:
p = subprocess.Popen(.., stdout=subprocess.PIPE, ..)
p.wait()
will deadlock with the subprocess waiting for data to be consumed, while
the Python process waits for its termination. So consume data, then wait
for termination.
(cherry picked from commit 83bcd13775323bec35d018223029e9a8b13179c8)
