[plugins] various small fixes/improvements

In plugins/housekeeping/gsd-ldsm-dialog.c
- Initialize GSList ignore_paths before use
- Use g_slist_prepend instead of _append in loop (more efficient), reverse after

In plugins/media-keys/msd-media-keys-manager.c
- Default to mate-terminal if terminal "exec" key is empty

In plugins/xrandr/msd-xrandr-manager.c
- Only start_or_stop_icon when the show icon key actually changes

Also, adapt this for media-keys plugin:
Don't use org.gnome.settings-daemon for volume_step setting
