OSD temperature display and calculations cleanup

Browse source 
Remove unnecessary decidegrees conversions as all temperature providers are in degrees celcius.

Fixed rounding for imperial units.

Fixed data type error in core temp warning element. Temperature is captured as int16 and can be negative but logic was using uint8 leading to an underflow for negative temperatures and a false alarm triggering.
