pid-ns-init: fix child process signal disposition (bug 675828)

Use subprocess.Popen to correctly configure the signal disposition
of the child process, since os.fork leaves the signal disposition
in a state which may be inappropriate for various signals including
SIGPIPE, SIGQUIT, SIGTERM, and SIGINT. For python implementations
other that CPython >= 3, use preexec_fn to manually configure the
signal disposition (I have found that this is necessary for CPython
2.7 and all PyPy versions tested, including PyPy3).
