perf tools: Fix accidentally preprocessed snprintf callback
struct sort_entry has a callback named snprintf that turns an entry into a string result. But there are glibc versions that implement snprintf through a macro. The following expression is then going to get the snprintf call preprocessed: ent->snprintf(...) to finally end up in a build error: util/hist.c: Dans la fonction «hist_entry__snprintf» : util/hist.c:539: erreur: «struct sort_entry» has no member named «__builtin___snprintf_chk» To fix this, prepend struct sort_entry callbacks with an "se_" prefix.
