selftests/bpf: adjust log_fixup's buffer size for proper truncation

Adjust log_fixup's expected buffer length to fix the test. It's pretty
finicky in its length expectation, but it doesn't break often. So just
adjust the length to work on current kernel and with follow up iterator
changes as well.
