Add input tests to surfaceflinger presubmit

One of the input tests was breaking a test from SurfaceFlinger_test.
The breakage only happened when it was executed before the SF test.

This only ended up affecting input presubmit, where the tests are
executed in this specific order. Meanwhile, input postsubmit and
surfaceflinger presubmit / postsubmit were fine.

The help catch these issues sooner in the future, add input tests to SF
presubmit.
