perf/core: Convert snprintf() to scnprintf()

Coccinelle reports a warning:

    WARNING: use scnprintf or sprintf

This LWN article explains the rationale for this change:

    https: //lwn.net/Articles/69419/

Ie. snprintf() returns what *would* be the resulting length,
while scnprintf() returns the actual length.

Adding to that, there has also been some slow migration from snprintf to scnprintf,
here's the shift in usage in the past 3.5 years, in all fs/ files:

                         v5.0    v6.0-rc6
   --------------------------------------
   snprintf() uses:        63         213
   scnprintf() uses:      374         186

No intended change in behavior.
