mprintf: fix integer handling in float precision

In the double output function when an extremely large width and
precision is set that reaches the libcurl maximum (325), the handling of
the precision part would do wrong which could lead to bad output.

Also: work-around for single-byte buffer snprintf overflow with mingw.

Extend test 557 to verify.

Coverity CID 1638751.

Closes #15988
