lib: cbprintf: improve coverage

Browse source 
Providing a literal width or precision that exceeds the non-negative
range of int does not appear to be rejected by the standard, but it
does produce a build diagnostic so we can't test it.  Switch to an
equivalent form that doesn't affect line coverage.
