fix: build x86_64 linux binary against glibc 2.31 (#738)

PR #725 dropped the Dockerized ubuntu:20.04 x86_64 build and started
building codecovcli_linux on the ubuntu-22.04 runner (glibc 2.35),
breaking the binary on older distros such as AL2023 (glibc 2.34).

Restore the ubuntu:20.04 x86_64 build in the Dockerized job following the
pre-#725 pattern (wildcard codecovcli_* path, glibc compatibility notes),
and use file_glob so build_linux.sh's renamed output is published as the
canonical codecovcli_linux asset.
