McuSupport: Support globbing in default paths

With this change default paths containing globbing characters will be
expanded to an available path.
example:  "sdk-*" will be replaced with "sdk-1.2.3" if the latter is
available.

To test the wildcards and make sure it works with QtCreator macros
a fake_kit was added containing fake packages.
