Commit Message

box: free cord_buf_global at thread exit

When an application thread exits, memory allocated for cord_buf_global
isn't freed, which triggers an ASAN memory leak report:

```
Direct leak of 168 byte(s) in 1 object(s) allocated from:
    #0 0x5b410ffb86d3 in malloc (src/tarantool+0xba76d3)
    #1 0x5b4110dcb951 in cord_buf_new src/lib/core/cord_buf.c:95:25
    #2 0x5b4110dcb824 in cord_buf_take src/lib/core/cord_buf.c:134:9
    #3 0x5b4110dcb75c in cord_ibuf_take src/lib/core/cord_buf.c:151:10
    #4 0x5b4110b67f59 in luaT_tuple_new src/box/lua/tuple.c:283:22

    #6 0x5b4110ec73c6 in lj_BC_FUNCC third_party/luajit/src/lj_vm.S:811
```

Fix this and add a test.
