Max Wipfli 84c0f98fb2 Kernel: Reimplement the dbgputch and dbgputstr syscalls ...

This rewrites the dbgputch and dbgputstr system calls as wrappers of
kstdio.h.

This fixes a bug where only the Kernel's debug output was also sent to
a serial debugger, while the userspace's debug output was only sent to
the Bochs debugger.

This also fixes a bug where debug output from one process would
sometimes "interrupt" the debug output from another process in the
middle of a line.
