[banshee] build: Don't copy duplicate libraries

[Gabriel Burt <gburt src gnome org>]

commit 7150c9967eae603c5f79c6c904e61dbb0b8c1dad
Author: Iain Lane <laney ubuntu com>

    build: Don't copy duplicate libraries
    
    GIO# and GTK#Beans both supply the same library, gio-sharp.dll. If we
    try to install both of these then automake falls over. Ensure that we
    only try to copy one of each library.
