ci: switch to Zig build toolchain and bump obikmer to 1.1.7

Replaces the musl-based static Linux build toolchain with Zig (`ziglang` via pip and `cargo-zigbuild`), removing `musl-tools` dependencies. The workflow now invokes `cargo zigbuild` for cross-compiling the static binary. Additionally, bumps the `obikmer` crate version to 1.1.7.
