tests/sprintf: Test floating printf on soft-fp targets too

There's no reason to limit testing floating point printf to platforms with
an FPU; neither the minimal C library nor picolibc even use floating point
instructions for printf. And even if they did, the toolchain should have
soft float support.

However, we do need to restrict picolibc testing to configurations with
floating point printf enabled.
