bpftool: Fix memory leak in do_build_table_cb
[ Upstream commit fa55ef14ef4fe06198c0ce811b603aec24134bc2 ]
strdup() allocates memory for path. We need to release the memory in the
following error path. Add free() to avoid memory leak.
Fixes: 8f184732b60b ("bpftool: Switch to libbpf's hashmap for pinned paths of BPF objects")
