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.
