[test][introspection] Enable MtouchNoSymbolStrip for debug|device in …

…order to avoid linking symbols meeded by test

@dalexsoto the fix is to not strip the executable please PR that
(it should probably go into master as well). This probably started
happening when Jeff implemented support for stripping debug builds
(previously the setting was ignored)
