crypto/bio: drop float formating for UEFI

Using floating point is not supported in UEFI and can cause build
problems, for example due to SSE being disabled and x64 calling
convention passing floats in SSE registers.

Avoid those problems by not compiling the formating code for floating
point numbers.
