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.</pre>
