[lldb/test] Fix TestAppleSimulatorOSType when multiple runtimes are installed

One can have multiple simulator runtimes installed, supporting
various generations of OSs. The logic in TestAppleSimulatorOSType
might select a rnutime older than the one targeted by the current
tools, preventing the executable from running. This commit changes
the test to look for the most recent runtime available instead.
