[glibmm] Remove sigc from the Doxygen excluded symbols

[Daniel Elstner <daniel src gnome org>]

commit 24683d74eaecc51b77ae27b36cd5d686692a7358
Author: Daniel Elstner <danielk openismus com>

    Remove sigc from the Doxygen excluded symbols
    
    * docs/reference/Doxyfile.in (EXCLUDE_SYMBOLS): Stop excluding
    the sigc namespace from the documentation since it apparently
    also removes the links to external documentation.  Also, with
    the latest changes in libsigc++ it seems no longer necessary to
    suppress the symbol.
