Alexander Moch 8e946b5ae8 cmd/ztest: avoid PATH_MAX stack allocation in ztest_get_zdb_bin() (#18085)
Calling realpath(path, buf) can trigger fortified header wrappers that
allocate a PATH_MAX-sized temporary buffer on the stack, exceeding the
4 KiB frame limit on some systems. Use the heap-allocating
realpath(path, NULL) form instead.
