Backport libglnx changes required to address CVE-2026-34078
* d/p/CVE-2026-34078/*.patch:

* d/p/GHSA-2fxp-43j9-pwvc/*.patch:

release before the branch was discontinued), originally from 1.16.1,
fixing a thread-safety issue in flatpak-portal

Add regression fixes taken from the upstream 1.16.5 release,
fixing various regressions introduced by fixing CVE-2026-34078
and improving test coverage
(Closes: #1132960)
* d/p/1.16.6/*.patch:
