Use TYPE for the standard output instead of io_putchar()

All stdout text from the C code of the paflof binary (e.g. all output
from printf() and friends) is currently only written via io_putchar()
to the hvterm console. If the user decided to use a VGA display instead,
the text is currently not shown there. This is especially affecting the
output of the TFTP boot functions which are using printf() to provide
valuable information like IP addresses and progress indication to the
user. Let's fix this nuisance by routing the stdout text through the
TYPE Forth word instead, so that it now shows up on both, the hvterm
console and the VGA console.
