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

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.
