Add a functionality test for DirectFB to ensure it compiles.

Some versions of the DirectFB headers are unclean and will cause Qt
compilation failures. So blacklist those versions. Version 1.5.3
(present in Fedora 16) is known to be buggy and gets disabled by this
patch.

The compile error was:
  qurlquery.h:169:5: error: ‘typeof’ was not declared in this scope

(qplatformcursor_qpa.h includes qevent.h which includes qurl.h which
includes that)

The error comes from the Q_FOREACH expansion. Note that Q_FOREACH uses
__typeof__, so it's supposed to be safe, unless someone ill-advised
goes and defines the GCC "safe" macro (double underscores on both
sides) to something else.
