directfb: fix error in *SetRegion* datatypes

DirectFB comes with incorrect declarations for *SetRegion* datatypes,
this breaks the build for some GFX Drivers. Also there are some headers
missend in the archive, this breaks some other modules of directfb that
not covered yet by the autobuilders.
And at least the configure script doesn't use a variable for the
imlib2-config script. That breaks crossbuilds of directfb in most cases.

Fixes:

+Call the imlib2-conf variable that are set by ac_cv_path_IMLIB2_CONFIG

+by the PATH variable.
+This is important for cross compiler that need to get the staging settings
