Panic spam and abort when interrupting execution with Ctrl+C

[jonas-schievink]

I've interrupted a hanging defmt-test executable by pressing Ctrl+C, and this happened:

(1/14) running `split_filters`...
(2/14) running `basic_roundtrip_fifo0`...
(3/14) running `basic_roundtrip_fifo1`...
(4/14) running `per_fifo_filters`...
(5/14) running `both_fifo_filters`...
