Subject: [PATCH] arc:kernel:perf_event.c : replaced sprintf with sysfs_emit()

Replaced sprintf() with sysfs_emit() in sysfs*_show() function in
perf_event.c file to follow the kernel's guidlines from
documentation/filesystems/sysfs.rst
This will improve consistency, safety, and makes it easier to maintain
and update in future.
