What this PR does / why we need it:

• Update sigs.k8s.io/bom to v0.6.0 and drop build for linux/s390x and windows/386

/assign @puerco @xmudrii @saschagrunert
cc @kubernetes/release-managers

from: #3419 (comment)

mmgrf the test is failing because `modernc.org/sqlite` which gets pulled in from the rpmdb module bom is using does not work in windows/386, not even when bumping it to the latest version :(

https://gitlab.com/cznic/sqlite/-/issues/169

So we are dropping the windows/386 because of lack of support and also for linux/s390x which maybe we dont have any release managers using that platform

Which issue(s) this PR fixes:

None

@cpanato: /override requires failed status contexts, check run or a prowjob name to operate on.
