sys/linux: support log_true_size field in bpf(2) PROG_LOAD
Commit [1] upstream added a new field to the bpf(2) PROG_LOAD command
for the kernel to return the buffer size that would be required to store
all logs. This is an output-only field so probably not much point in
fuzzing it, so let's fix it to 0.
