tree-wide: switch initrd generators back to gnu cpio

Browse Source 
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)"
