Check shipped libraries against the Frame; keep OpenSSL out of the bundle (iteration 2, step 7)

package-release.sh refuses a package whose ELF files need newer glibc or
OpenSSL symbol versions than the Frame has (D35); only the version needs
section counts. The Qt bundler resolved libmosquitto's dependencies and
shipped Debian's OpenSSL 3.5; libssl/libcrypto are now excluded, since
SteamOS provides OpenSSL 3. Phase 3 of iteration 2 is done; PROGRESS.md
has the manual checklist for phase 4.
