Redirect printf to other function (like uart) to take log

The macro MUNIT_OUTPUT_FILE might be useful. At a glance, it seems to handle most of the library's main output. (Help message is hard-coded to printf, puts though.)

Yeah, but seem not work at my system when I can't use the fprintf function.

Isn't this is often something that is provided by the board support package for your embedded system? The BSP that gets generated with my Xilinx Arm Cortex-M processor has a configuration file that indicates what uart the printf function outputs to.
