package_rpm: use zstd instead of xz

zstd has similar time and space performance in compression but is
vastly faster in decompression, which benefits rootfs creation
(especially when installing very large packages) and on-target
package installation.

Also, ensure ZSTD_THREADS doesn't change sstate checksums. The
detailed explanation is in the commit making similar change for
XZ_THREADS.
