Fix RPATH issues with absolute paths

Minor changes to help writing patches against OCCT.
Run TDataXtd_test only if OCE_DISABLE_X11 option is not set

It depends on TKCAF and TKXCAF modules which are built only
if OCE_DISABLE_X11 is not set.

Moreover TKXCAF is built by DATA_EXCHANGE and not OCAF, so
we must check against DATA_EXCHANGE instead of OCAF.
Bumped oce version to 0.11-dev
Upgrade to OCCT 6.5.4

Apply patches from 99ae871 on official/6.5.4.
Replaced config.h with oce-config.h in Image/Image_AlienPixMap.cxx
On OSX, native OpenGl header should never be called, but only the X11 GL headers: OCE only supports X11, not Cocoa
Added Font to TKService
Updated BuildToolit.cmake: OSD_FontMgr.cxx was renamed to Font_FontMgr.cxx
Additional TKCAF dependency upon TKBO
Replaced config.h with oce-config.h in QAViewer2dTest/QAViewer2dTest_ObjectCommands.cxx
Drop X11_FONT_PATH, it is no more needed

Upstream moved OSD_FontMgr.cxx into TKService, so XGetFontPath
can now be used.
Drop HAVE_FTGL_NEWER212 macro, this is no more needed

Upstream now supports ftgl 2.1.3rc5.
Fix installation of DrawResources
Bumped ABI_SOVERSION since OCCT6.5.4 changes are binary incompatible with previous version
