Library linter reports false positives for dependencies provided via gpu-extension mesa slot; untriaged, no maintainer response

Suggested action: needs triage

Reason: The issue has no labels, no maintainer comments, and no assignee after 50 days. It reports a legitimate bug where the library linter produces false positives for dependencies (e.g. libX11, libxml2) that are provided through the gpu-extension's mesa slot. A maintainer needs to triage and confirm whether this is a known limitation or a fixable bug.

Issue body

oHi, A 'gpu'-linter has been added with snapcraft 9.0+ to check whether the display libraries are called through the gpu-extension ; this is nice. Yet, using the gpu-extension, the library-linter fails to output a relevant report as it cannot see the libraries dependencies through the mesa snaps slot. Thus making it impossible to check automatically the dependencies. e.g. ``` Running linters...

Especially with all the limitations for snap-as-libraries (one version installed, no possible version check) and extensions (forced to build with current stable main channel ; hard to track revisions changes at running).
