    gi-test: Fix gir file tests
    
    The os.path.splitext(targetname)[0] may return the fullpath of the
    target gir, which subsequently may make the path constructed to locate
    the *-expected.gir to be incorrect, causing the gir tests to fail.
    
    For example, the sources might reside in d:\git_repos\gi and the build
    is carried out in d:\gi.build, and when the TypeDefs gir test is run,
    the script would construct the path for the reference gir to be at:
    
    D:\\gi.build\\tests\\scanner\\Typedefs-1.0-expected.gir
    
    instead of
    
    D:\\git_repos\\gi\\tests\\scanner\\Typedefs-1.0-expected.gir
    
    Fix this by going further to get only the filename of the targetname so
    that we can construct the path to the reference gir files correctly.
