This is a serious pitfall as e.g. run_cmd(['python', '-c' , 'print(1)']) would be interpreted as `bash -c python -c 'print(1)'`, i.e. the arguments are passed to bash and not to python! Allow to opt-in into that by passing shell=True explicitely.

edit (by @boegel): only occurrence in central easyblocks was in custom easyblock for TensorFlow, which was fixed in easybuilders/easybuild-easyblocks#2469 (I went through all easyblocks, didn't find other instances of passing a list of strings to
run_cmd*)
