waldump: fix use-after-free in search_directory(). After closedir() dirent->d_name is not valid anymore. As there alerady are a few places relying on the limited lifetime of pg_waldump, do so here as well, and just pg_strdup() the string.
The bug was introduced in fc49e24fa69a. Found by UBSan, run locally. Backpatch: 11-, like fc49e24fa69 itself.
