sim: callback: add printf attributes
This helps these funcs get printf format checking coverage.
The sim-io.c hack as a result is a bit unfortunate, but the compiler
throws warnings when printing with empty strings. In this one case,
we actually want that due to the side-effect of the callback halting
execution for us.
