autotools: build GNOME Bluetooth panel plugin (MB #7089)

The GNOME Bluetooth panel plugin needs to be installed into
the location used by the system. We guess what that location might be by
installing into `pkg-config --variable=libdir gnome-bluetooth-1.0`/plugins.

Because this location might not be writable, compiling the plugin is
off by default. It can be enabled with --enable-gnome-bluetooth-panel-plugin
which depends on the libgnome-bluetooth-dev files.

Shared libraries must be enabled when enabling the plugin. Not currently
checked by configure.

 The build system is the normal autotools system. See INSTALL for
 general instructions how to use that and "./configure --help" for
 SyncEvolution specific options.
