Originally, we switched to bsdtar from libarchive to solve a reproducibility issue related to hardlinks As of gnu cpio 2.14 the --ignore-dirnlink option is introduced and now included in --reproducible, which solves this issue By switching back, we are in turn solving an issue in libarchive >=3.7.5 erroring out with "Error reading archive -: (null)" Change-Id: Ib6140d599b6547d8e941b0251ce996e303c41fa6
