[lldb] fix SourceManagerTestCase freeze

[daniilavdeev]

Currently lldb testsuite requires some interactive input:

test_artificial_source_location (TestSourceManager.SourceManagerTestCase)
There is a running process, kill it and restart?: [Y/n]

This patch sets lldb auto-confirm flag to true before SourceManagerTestCase start, so the test doesn't freeze now.

On what platform are you seeing this problem? None of Linaro's bots have an issue with the test.

Is it because you're using remote debugging and only in that case it prompts for this?

I've encountered with the problem using remote debugging at first, but then I was able to reproduce it on x86 host platform with command looks like this (I don't remember exactly):

python3 lldb/test/API/dotest.py -A x86-64 -C build/bin/clang --executable build/bin/lldb -f SourceManagerTestCase lldb/test/API

Please dig into why it's failing, remotely or locally whatever you can reproduce. I doubt the reason is anything sinister but I'd like to know what it is before approving anything.
