xfce4-sensors-plugin: Change defaults to useful ones

Every time I added xfce4-sensors-plugin to panel xfce4-sensors-plugin suggested
sensors not exactly useful. So change defaults:

* remove lmsensors
* make sysfsacpi work and don't disable it because that's where embedded
  machines drop useful information

Background: Have spent lots of efforts to get Raspi4 cooled properly while
running at gouvernor 'performance' and rendering music. Would like to see if it
really wears a cool hat [1]
