[PATCH 1/3] imager sbom: simplify invocation of debsbom tool

['Felix Moessbauer' via isar-users]

We don't need to create the output directory upfront, as bwrap
internally does this on bind-mounting. Further, we avoid being extra
verbose to align the debsbom CLI with the other invocations.

[PATCH 3/3] rootfs sbom: directly use captured apt state without extraction

['Felix Moessbauer' via isar-users]

Since version 0.10 debsbom is capable of reading the apt state from a
tarball instead of an extracted rootfs. By that, we can remove the
manual extraction of the apt state and instead directly pass the tarball
to debsbom.

Hi, please don't merge yet. Debsbom 0.10.1 has two bugs calling for a
0.10.2 release. Once released, I'll send a v2 which directly updates to
0.10.2.
