    tools/gen_scripts/: Update for pango built with meson
    
    When pango is built with meson instead of autotools, generated .h and .c
    files are stored in pango/build/pango. Files in that directory shall be read
    when pango_docs.xml and the .defs files are generated.
    
    Don't read private and internal .h files.
