bpftool: Ensure bytes_memlock json output is correct
If a BPF map is created over 2^32 the memlock value as displayed in JSON
format will be incorrect. Use atoll instead of atoi so that the correct
number is displayed.
```
$ bpftool map create /sys/fs/bpf/test_bpfmap type hash key 4 \
value 1024 entries 4194304 name test_bpfmap
$ bpftool map list
1: hash name test_bpfmap flags 0x0
key 4B value 1024B max_entries 4194304 memlock 4328521728B
$ sudo bpftool map list -j | jq .[].bytes_memlock
33554432
