[lldb][NFC] Force some logging on to TestCortexMExceptionUnwind.py
to possibly debug why this test fails on the
lldb-remote-linux-ubuntu CI bot. I'm sure the Target ArchSpec is
somehow ending up _not_ armv7m-apple-* like it should be, but I'd
like to gather a little more info before I just give up on running
this test on linux systems.

- # The Darwin ABIMacOSX_arm diverges from AAPCS and always uses r7 for

- # thumb. So its CreateDefaultUnwindPlan picks the correct register for
- # the frame pointer, and we can walk the stack.
- # ABISysV_arm::CreateDefaultUnwindPlan will only get one frame and
