Frank Gevaerts 3665eecf47 Increase set_time_screen() buffer size for hosted to keep the compiler happy. 
The format strings in the snprintf can in theory need 60 characters
This will not happen in practice (because seconds are 0..60 and not
full-range integers etc.), but -D_FORTIFY_SOURCE will still warn
about it, so we use 60 characters for HOSTED to make the compiler
happy. Native builds still use 20, which is enough in practice.
