[CI] Generic pypanda tests broken but reporting passing

[AndrewFasano]

It seems that generic_tests.py as run by our CI is failing, but the tests are reported as passing. From https://github.com/panda-re/panda/actions/runs/6148260094/job/16689846816?pr=1352 we can see it downloads some stuff and then prints:

It appears to fail in the first part of the test of CLI panda: https://github.com/panda-re/panda/blob/dev/panda/python/tests/generic_tests.py#L66

I suspect that it could have something to do with it claiming that it's missing both nc and panda-system-X

failed to run command ‘panda-system-x86_64’: No such file or directory
