bpf-program: make bpf_program_load_kernel() idempotent

Let's "seal" off the BPF program as soo as bpf_program_load_kernel() is
called, which allows us to make it idempotent: since the program can't
be modified anymore after being turned into a kernel object it's safe to
shortcut behaviour if called multiple times.
