Only compile dprintf/vdprintf if DEBUG_PORT is defined
We really, really don't want to accidentally spew output to a debug
port in production, so make it obligatory to define DEBUG_PORT or
DEBUG_STDIO in order for the debugging code to be compiled in. Since
DEBUG_STDIO just turns the debugging code into stdio references, we
only need to compile the code for the DEBUG_PORT case.
Add a commented-out line to mk/devel.mk to make it easier for users.
