[PATCH] tests/functional/test_arm_sx1: Check whether the serial console is working

[Thomas Huth <thuth@redhat.com>]

The kernel that is used in the sx1 test prints the usual Linux log
onto the serial console, but this test currently ignores it. To
make sure that the serial device is working properly, let's check
for some strings in the output here.

While we're at it, also add the test to the corresponding section
in the MAINTAINERS file.
