'save_file' is used both for holding the -w command-line argument as
well as the current filename that is being written. In ringbuffer mode,
the former is already freed while the latter changes after rotation. Be
sure to free all ringbuffer filenames on exit.
Fixes test failures due to ASAN reporting memory leaks for:
test_dumpcap_ringbuffer_filesize
test_dumpcap_pcapng_single_in_multi_out
test_dumpcap_pcapng_multi_in_multi_out
test_dumpcap_ringbuffer_packets
