[PATCH RESEND v2] perf/x86/intel/uncore: Use sysfs_emit() in uncore_event_show()

[Thorsten Blum <thorsten.blum@linux.dev>]

Replace sprintf() with sysfs_emit() in uncore_event_show(). sysfs_emit()
is preferred for formatting sysfs output because it provides safer
bounds checking.

Add a terminating newline as suggested by checkpatch.
