set CRC_SELF_SUFFICIENT=0 to bypass vsock based check

The `crc-self-sufficient-env.sh` script was determining
the env as self-sufficient also during startup with crc

This sets `CRC_SELF_SUFFICIENT=0` and forces the script
to exit early before reaching the `vsock` check

this lets the bundle to start with crc and also in  the
cloud with `mapt` which will set  `CRC_SELF_SUFFICIENT`
via cloud-init
