Make conditionals on BIOSWAIT consistent with usage in io.c.

If you had 'BOOTWAIT=0' in your /etc/make.conf then biosboot wouldn't
compile.  It was '#if' in io.c and '#ifdef' in probe_keyboard.c so I
changed the latter to '#if'.

Even if BOOTWAIT is undefined then '#if BOOTWAIT' becomes
'#if 0' so it should compile either way with this change.
