selftests: net: bpf_offload: print loaded programs on mismatch
The test sometimes fails due to an unexpected number of loaded programs. e.g
FAIL: 2 BPF programs loaded, expected 1
File "/usr/libexec/kselftests/net/./bpf_offload.py", line 940, in <module>
progs = bpftool_prog_list(expected=1)
File "/usr/libexec/kselftests/net/./bpf_offload.py", line 187, in bpftool_prog_list
fail(True, "%d BPF programs loaded, expected %d" %
File "/usr/libexec/kselftests/net/./bpf_offload.py", line 89, in fail
tb = "".join(traceback.extract_stack().format())
However, the logs do not show which programs were actually loaded, making it
difficult to debug the failure.
Add printing of the loaded programs when a mismatch is detected to help
troubleshoot such errors. The list is printed on a new line to avoid breaking
the current log format.
