kunit: qemu_configs: Disable faulting tests on 32-bit SPARC

The 32-bit sparc configuration (--arch sparc) crashes on
the kunit_fault_test. It's known that some architectures don't handle
deliberate segfaults in kernel mode well, so there's a config switch to
disable tests which rely upon it by default.

Use this for the sparc config, making sure the default config for it
passes.
