console: Use only 0x00 as line separator for console recording

Browse source 
In case character 0x20 (space) is used as line separator,
character 0x9 (tab) is treated end of line. Commands which
output a lot of tabs, i.e. various tree printing commands
like 'fdt print' then end up generating a lot of newlines
in the recorded output, and the recorded output is corrupted.

Use character 0x00 (NUL) as separator instead to treat the
tabs as valid part of recorded line.
