[Xamarin.Android.Build.Tasks] Add new Unit test for AOT

Our AOT system needs to work when a user uses
non ASCII characters and spaces. This commit
updates our BuildAotApplication unit test to
use both spaces and UTF8 based characters.
This will make sure that in future versions of
mono we do not regress supporting those kinds
of paths.
