[PATCH] automation: introduce TEST_TIMEOUT_OVERRIDE

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

TEST_TIME is set as a CI/CD project variable, as it should be, to match
the capability and speed of the testing infrastructure.

As it turns out, TEST_TIME defined in test.yaml cannot override
TEST_TIME defined as CI/CD project variable. As a consequence, today the
TEST_TIME setting in test.yaml for the Xilinx jobs is ignored.

Instead, rename TEST_TIMEOUT to TEST_TIMEOUT_OVERRIDE in test.yaml and
check for TEST_TIMEOUT_OVERRIDE first in console.exp.
