gnu: libpfm4: Fix build error.
------
For some reason, the build recently failed with:
pfmlib_perf_event_pmu.c:349:36: error: ?%s? directive output may be truncated writing up to 255 bytes into a region of size between 0 and 4095 [-Werror=format-truncation=]
349 | snprintf(d2path, MAXPATHLEN, "%s/%s", debugfs_mnt, d1->d_name);
| ^~
pfmlib_perf_event_pmu.c:349:3: note: ?snprintf? output between 2 and 4352 bytes into a destination of size 4096
349 | snprintf(d2path, MAXPATHLEN, "%s/%s", debugfs_mnt, d1->d_name);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
