WSL fix for terminate process in audio

[OgulcanCelik]

added @ryanfox's fix (#861) to the audio:

Prevents proc.terminate() from throwing an exception when the process has already terminated.

It's the final fix for #765 I believe.

• If this is a bugfix, I have provided code that clearly demonstrates the problem and that works when used with this PR
• I have added a test to the test suite, if necessary
• I have properly documented new or changed features in the documention, or the docstrings
• I have properly documented unusual changes to the code in the comments around it
• I have made note of any breaking/backwards incompatible changes

Is Travis build stuck?

I'm using this fix by myself since October and did not come up with any issues so far.

@OgulcanCelik For some reason the notification did not pass through, build seems fine.

However, there are plenty of test cases that load VideoFileClip and Travis build runs fine on master, so it's possible that:

• this has already been fixed on master, possible with Fix for #926 #927
• this is specific to certain files, in which case we should have a test case for reproducing the issue and making sure it's fixed

Could you have a look ? Thanks for your contribution

@Overdrivr
Hello,
Just checked and yeah it seems like the issue on WSL fixed with #927. However, I guess pip package isn't updated yet, so I tried with manually implementing the fix, works fine. Thanks!
