selftests/bpf: Print log buffer for exceptions test only on failure
Alexei reported seeing log messages for some test cases even though we just wanted to match the error string from the verifier. Move the printing of the log buffer to a guarded condition so that we only print it when we fail to match on the expected string in the log buffer, preventing unneeded output when running the test.
