Update a bit for the changes in FreeType 2.7.1

Our test case relies on the outcome of the family property from freetype though,
it was changed in 2.7.1:

  - PCF family names are made more `colourful'; they now include the
    foundry  and information  whether they contain  wide characters.
    For example,  you no longer get `Fixed' but  rather `Sony Fixed'
    or `Misc Fixed Wide'.
