Added support for generate_sbom through a finalize script. Tested with mkosi 22 on Debian Testing. The used version needs to support configuration dir feature and multiple scripts of same name (mkosi v18) Mkosi builds in using tmpfs and other security features and removes everything after building, so it is not possible to call generate_sbom after mkosi run on the buildroot. Content of `/.build` needs to be copied into a place under `/usr` because most host directories are hidden from mkosi (introduced in mkosi v20)
The name for the spdx profile can be set using the macro `%mkosi_spdx_name` in the project configuration. Default is `image` if not set.

No special macro is needed to set the filename, take ImageID (if set) or default to "image". Also no sha256 generateion needs to be done, mkosi creates it for all files in $OUTPUTDIR in "$IMAGENAME.SHA256SUMS"

Tested with mkosi 22.
If Buildflag sbom is set a mkosi.finaliz script is created in a mkosi.conf.d subdirectory to not overwrite possible existent scripts and will be called at the end to call generate_sbom before mkosi creates the image.
The used version needs to support configuration dir feature and multiple scripts of same name (mkosi v18)
Mkosi builds in using tmpfs and other security features and removes everything after building, so it is not possible to call generate_sbom after mkosi run on the buildroot.
Content of
/.buildneeds to be copied into a place under/usrbecause most host directories are hidden from mkosi (introduced in mkosi v20)The name for the spdx profileis set by the ImageID of mkosi.conf. Default is
