dtcalc: Resolve "format not a string literal and no format arguments [-Wformat-security]" warnings.

Browse source 
Fix warnings related to secruity concerns on varargs functions. By specifying
"%s" on single string calls to sprintf() (and related) it's not possible to
have a % in the input string causing random data to be read off the stack.
