Function skopeo_bin

crates/utils/src/lib.rs:42–47

Return the skopeo binary path, honouring the `BOOTC_EXP_EXTERNAL_CONTAINER_TOOL` environment variable so callers can substitute an alternative tool (e.g. `dtool`) without hard-linking it as `/usr/bin/skopeo`. The _EXP prefix indicates this interface is experimental and subject to change.
