misc/ios: dump logs for failing lldb sessions to stdout

Browse Source 
The iOS test harness dumps the output of its lldb session to stdout,
but only if the lldb session was successfully started.
Make sure the log is always dumpede, so that lldb startup failures
such as

lldb setup error: exited (lldb start: exit status 253)

can be diagnosed.

For the iOS builders.
