unable to index filesystem for amazonlinux images

[crazy-max]

• related to vendor: bump github.com/anchore/syft from 0.98.0 to 0.105.0 docker/buildkit-syft-scanner#94

What happened:

Latest syft (0.104.0) fails to index amazonlinux images when scanning root using source.NewFromDirectory https://github.com/docker/buildkit-syft-scanner/blob/7f1fed0d3a1494365ff612d81d1c90f777ce9f81/internal/target.go#L37-L43:

unable to get file resolver: unable to create directory resolver: unable to index filesystem path="/run/src/extras/sbom-base/dev/fd/2": unable to index branch="/run/src/extras/sbom-base/dev/fd/2": lstat /proc/1/fd/pipe:[33575]: no such file or directory

What you expected to happen:

Be able to scan

Steps to reproduce the issue:

Repro with this Dockerfile using BuildKit Syft Scanner: https://github.com/docker/buildkit-syft-scanner/actions/runs/7883917948/job/21511817145?pr=94#step:7:75

FROM amazonlinux:2 AS base
ARG BUILDKIT_SBOM_SCAN_STAGE=true
RUN yum install -y findutils

docker buildx build --sbom=true .

Anything else we need to know?:
