postmarketos-ui-xfce4: remove Custom DPI settings

Hi, while playing with the xfce4 ui I've noticed that: Appearance -> Fonts -> Custom DPI Settings 96 is enabled by default. I think this should be instead being disabled by default as it makes UI elements microscopic. DPI settings should be set to sane defaults by device maintainer or developer in xorg.conf Monitor section with options like:

DisplaySize 68 121 # In millimeters (gives DPI 403 for me, still a little high, DPI 320 would be better)

Option "DPI" "480 x 480" # or whatever value

P.S.: An alternative would be to set Window scaling to 2 in xfce4 settings. This still needs custom DPI enabled and set to 140 to look good (more or less...) for my taste.

So alternative 1) Disabling Custom DPI settings is still easier as UI elements are big enough so that the end user can change settings to his liking.

Hints, critics, improvements are welcome.
