[PATCH v2 02/17] tests/qtest/npcm7xx: Replace deprecated sprintf() with g_strdup_printf()

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

Replace sprintf() by safer g_strdup_printf() to fill the QOM path
and property names. This silences when using Apple clang 17.0.0:

  ../tests/qtest/npcm7xx_adc-test.c:140:5: warning: 'sprintf' is deprecated [-Wdeprecated-declarations]
