[lldb] [Host/netbsd] Set Arg0 for 'platform process list -v'

[wallace]

Supposedly Arguments shouldn't contain Arg0 (https://reviews.llvm.org/source/llvm-github/browse/master/lldb/include/lldb/Utility/ProcessInfo.h$96)
I think you just need to change the dump method that prints to platform process list.

I don't know if NetBSD is doing something different, but the general dump method for ProcessInfo prints first arg0 and then the other args https://reviews.llvm.org/source/llvm-github/browse/master/lldb/source/Utility/ProcessInfo.cpp$229-235

Hmm, I think I see how it's supposed to work. I'm going to update the patch after I test it.

Ok, how does that look instead? ;-)
