[PATCH] selftests: iommu: add config needed for iommufd_fail_nth

[Muhammad Usama Anjum]

Add FAULT_INJECTION_DEBUG_FS and FAILSLAB configurations which are
needed by iommufd_fail_nth test.

While building and running these tests on x86, defconfig had these
configs enabled. But ARM64's defconfig doesn't enable these configs.
Hence the config options are being added explicitly in this patch.
