Busco doesn't exit with an error when one of the subtools is killed, or print a suitable error message

[mahesh-panchal]

Describe the bug

Metaeuk in Busco was likely killed due to using up too much memory, but Busco did not detect it and just reported Metaeuk found no genes.

To Reproduce
Steps to reproduce the behavior:

1. Run busco without enough memory and let slurm kill Metaeuk for using too much memory.

Expected behavior

My expectation was that Busco would detect Metaeuk had not finished correctly.
