[OE-core] [PATCH 1/2] testimage: Allow testing on QEMU machines with a single serial port

[Alejandro Hernandez Samaniego]

commmit 6cde67d0a84 enables the use of qemurunner on machines that
only have a single serial port, but still sets the default value
as serial_ports=2 if not provided.

The testimage class does not call qemurunner with a serial_ports
argument, hence always defaulting to two.

Pass the serial_ports argument from the testimage class to allow
tests to run on QEMU machines with a single serial port.
