Generate app-specific machine IDs derived from the machine ID defined in
/etc/machine-id and an application ID.
Unlike the default machine ID, which should be considered "confidential", this implementation uses HMAC-SHA256 to generate an app-specific machine ID which could be used in less secure contexts.
This implementation is based on systemd's sd_id128_get_machine_app_specific().
See man machine-id(5)
and man sd_id128_get_machine(3)
for details.
