[PATCH] selftests/powerpc: Use snprintf to construct DSCR sysfs interface paths

Currently sprintf is used, and while paths should never exceed the size of the buffer it is theoretically possible since dirent.d_name is 256 bytes. As a result this trips -Wformat-overflow, and since the test is built with -Wall -Werror the causes the build to fail. Switch to using snprintf and
