swig: upgrade to 2.0.9 and add patch to fix swiglib

* FindSWIG.cmake is using swig -swiglib to find swig.swg and set
  SWIG_DIR without that patch swig -swiglib reports absolute path
  to datadir how it was on builder which created sstate archive,
  reusing swig from sstate results in invalid path hardcoded in
  swig binary and FindSWIG reporting missing swig

* unfortunately it's not using any config file we could make
  relocateble with SSTATE_SCAN_FILES

* LICENSE-UNIVERSITIES change is only formal
