KAFKA-20063 Fix Docker build hang by reordering tar extraction before…
(#21296)
The Docker build for Alpine images intermittently hangs during the tar
extraction phase. This is caused by gcompat being loaded into the
process space during the preceding gpg verification step, which
interferes with Alpine's tar implementation and causes a deadlock.
