[Rpm-maint] [rpm-software-management/rpm] zstd compression: port to the new API. (#1303)

[marxin]

Port zstd compression to the new API (ZSTD_compressStream2).

My motivation is to eventually enable multi-threaded compression which can help packages like Firefox where there's a single huge rpm that is being compressed.

Once the change is accepted, the following one-liner will enable parallel compression:
```c
ZSTD_CCtx_setParameter(cctx, ZSTD_c_nbWorkers, 4);
```
