Re-raise the same type of exception we get in launch_tor()

On #17946 germn argues we should re-raise our original exception type and I can can see that. In normal scenarios we should *only* raise an OSError (as documented), but if the caller invokes an exception within us (like KeyboardInterrupt) then no reason not to give them that. --- stem/process.py | 8 +------- test/integ/process.py | 6 +++--- 2 files changed, 4 insertions(+), 10 deletions(-)
