Move Dockerfile(s) from musl to glibc

Musl is tier 2 on rust support, and glibc is tier 1.
https://doc.rust-lang.org/nightly/rustc/platform-support.html
Generally, glibc rust is reported to be more performant. Could vary due
to any other reason, but in my testing, builds were up to 50% faster
(for docker cross-compilation amd64->arm64 at least).
