[libwnck] build: Add --enable-tools to enable/disable installation of tools

[Vincent Untz <vuntz src gnome org>]

commit 21538b70a9d493d33021b806f830091591f66815

    build: Add --enable-tools to enable/disable installation of tools
    
    This helps make libwnck 2.x and 3.x be parallel-installable since they
    conflict for wnckprop and wnck-urgency-monitor.
