Mark test fixture objects __maybe_unused since they will not be used
when there are fixture variants (the variants will be used instead).
This fixes the VFIO selftest build with clang and -Werror:
vfio_dma_mapping_mmio_test.c:106:1: error: variable
'_vfio_dma_mapping_mmio_test_map_full_bar_object' set but not used
[-Werror,-Wunused-but-set-global]
106 | TEST_F(vfio_dma_mapping_mmio_test, map_full_bar)
| ^
./../kselftest_harness.h:398:2: note: expanded from macro 'TEST_F'
398 | __TEST_F_IMPL(fixture_name, test_name, -1, TEST_TIMEOUT_DEFAULT)
| ^
./../kselftest_harness.h:470:33: note: expanded from macro '__TEST_F_IMPL'
470 | static struct __test_metadata
*_##fixture_name##_##test_name##_object; \
