Add configure and CMake checks for X11/Xregion.h.

Browse Source 
Configure and CMake now both check if X11/Xregion.h exists on the
build system and set HAVE_X11_XREGION_H in config.h accordingly.

src/Fl_Pixmap.cxx: modified to use the configure test as proposed by Manolo
in fltk.coredev on Dec 13 2015 in thread "Using X11 backend on OS X".
