ci: raise glibc symbol ceiling to 2.34

The LZMA multithreading support links pthread symbols, which carry
GLIBC_2.34 versions when built on glibc >= 2.34 runners; published
v2.3.0 prebuilds already require 2.34 and it remains compatible with
Ubuntu 22.04, Debian 12, and RHEL 9. The 2.33 ceiling predated that.
