    tests/kms_frontbuffer_tracking: Fix Y alignment in the scaledprimary
subtest, v3.

    This is hidden behind the other kms_frontbuffer_tracking failures,
    but is its own fail.

    On gen9/gen10 we fail the scaledprimary tests because FBC refuses
    to be enabled with "plane Y offset is misaligned".
    Looking at the kernel, this is a workaround for FIFO underruns
    which can be tested as well. Test that with the right alignment, FBC
    is enabled and with misalignment FBC is disabled on <= gen10.
