This commit is a follow up of b7028af (entrypoint.sh: Update help
text so that current image name is used)
It ensures that the suggested script in the help text doesn't include ":"
in its name.
Assuming DEFAULT_DOCKCROSS_IMAGE is set to "dockcross/imagename:latest"
Instead of suggesting:
[...]
# docker run --rm dockcross/imagename:latest > dockcross-imagename:latest
# chmod +x dockcross-imagename:latest
[...]
it will now suggest
[...]
# docker run --rm dockcross/imagename:latest > dockcross-imagename-latest
# chmod +x dockcross-imagename-latest
[...]
