Large Text is on: show only GPS fixes label, hide visible

@garvankeeley There is a layout problem regarding the display of available GPS satellites if `Accessibility > Large text` is enabled.
This PR fully fixes the problem for #used satellites <= 9. When more satellites are in use, the number of available satellites is now cut off. I could not find another fix without breaking what was discussed in #1051.
Do you think this is an improvement? Any other ideas?
