Because of the parallel processing of `import-sql` the error message is printed in the middle of the output. With this PR the error is displayed again at the end:
![grafik](https://user-images.githubusercontent.com/19800037/133897373-656ed3d0-e580-4f67-9290-0e83949d63d7.png)

Issue: openmaptiles/openmaptiles-tools#370

```
awk '1{print; fflush()} $$0~".*ERROR" {txt=$$0} END{ if(txt){print "\n*** ERROR detected, aborting:"; print txt; exit(1)} }'
```
Explanation:
- `1{print; fflush()}` means if true then print output -> `1{}` same as `if(true){}`
- `$$0~".*ERROR" {txt=$$0}` get first argument `$$0` (line of output) and check if it contains (regex string) `ERROR`. If true save line to var `txt`: `{txt=$$0}`
- `END{ ... }` if last line of output is reached
- `if(txt){print "\n*** ERROR detected, aborting:"; print txt; exit(1)}` if error was found in a line / var `txt` is existing print it out

The #373 can be merged as is. No need to wait. The issue is that OMT itself wouldn't print errors "as nicely" with it, but its not a big deal.
