[PATCH 2/2] test.py: check ubconfig exists before using it

[David Lechner]

Add a check in the show_timings() function of test/py/test.py to ensure
that the global `ubconfig` variable was actually created before trying
use it.

If tests fail early, e.g. because --build failed, ubconfig may not have
been created yet and results in an exception in an atexit handler.
Adding this check avoids unnecessary noise in the output.

    Exception ignored in atexit callback: <function cleanup at 0x7de475ea6b60>
    Traceback (most recent call last):
    File "u-boot/test/py/conftest.py", line 669, in cleanup
        show_timings()
    File "u-boot/test/py/conftest.py", line 616, in show_timings
        if ubconfig.timing:
        ^^^^^^^^
    NameError: name 'ubconfig' is not defined
