python3-docker-compose: import fastentrypoints

Browse Source 
The docker-compose project is using console_scripts which hence imports
pkg_resources which is very slow at starting time, see:
https://github.com/pypa/setuptools/issues/510

This could be workaround by importing fastentrypoints module.

Some tests:

Before the patch, on a colibri-imx8x machine:

$ time docker-compose
```

real	0m5.108s
user	0m4.761s
sys	0m0.272s
```

After the patch, on a colibri-imx8x machine:

$ time docker-compose
```

real	0m3.526s
user	0m3.249s
sys	0m0.235s
```

Have verified the patch with:
https://docs.docker.com/compose/gettingstarted
