perf hists: Fix snprintf() in hists__scnprintf_title() UID filter path
hists__scnprintf_title() accumulates formatted output into a buffer using scnprintf() for all filter clauses except the UID filter, which uses snprintf(). If the buffer fills up and snprintf() returns more than the remaining space, printed exceeds size and the next 'size - printed' underflows, causing later scnprintf() calls to write past the buffer. Switch the UID filter clause to scnprintf() to match the rest of the function.
