ladspa-sink: Add sink_master argument to enable filter-apply to load the module

Browse source 
Currently, module-filter-apply cannot load module-ladspa-sink because filter-apply
provides the argument "sink_master" but ladspa-sink expects "master" instead.

Therefore this patch adds the sink_master argument to module-ladspa-sink.

Additionally, the autoloaded argument was also added.
