genirq/test: Depend on SPARSE_IRQ
Some architectures have a static interrupt layout, with a limited number of
interrupts. Without SPARSE_IRQ, the test may not be able to allocate any
fake interrupts, and the test will fail. (This occurs on ARCH=m68k, for
example.)
Additionally, managed-affinity is only supported with CONFIG_SPARSE_IRQ=y,
so irq_shutdown_depth_test() and irq_cpuhotplug_test() would fail without
it.
Add a 'SPARSE_IRQ' dependency to avoid these problems.
Many architectures 'select SPARSE_IRQ', so this is easy to miss.
Notably, this also excludes ARCH=um from running any of these tests, even
though some of them might work.
Fixes: 66067c3c8a1e ("genirq: Add kunit tests for depth counts")
