selftests/bpf: fix a typo in map in map test 

Commit fbeb1603bf ("bpf: verifier: MOV64 don't mark dst reg unbounded")
revealed a typo in commit fb30d4b712 ("bpf: Add tests for map-in-map"):
BPF_MOV64_REG(BPF_REG_0, 0) was used instead of
BPF_MOV64_IMM(BPF_REG_0, 0).

I've noticed the problem by running bpf kselftests.
