[PATCH] automation: restore CR filtering

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

After commit c36efb7fcea6 ("automation: use expect to run QEMU") we lost
the \r filtering introduced by b576497e3b7d ("automation: remove CR
characters from serial output"). This patch reintroduced it.

Fixes: c36efb7fcea6 ("automation: use expect to run QEMU")
