When using `bpftool map dump` with map_of_maps, it is usually
more convenient to show the inner map id instead of raw value.
We are changing the plain print behavior to show inner_map_id
instead of hex value, this would help with quick look up of
inner map with `bpftool map dump id <inner_map_id>`.
To avoid disrupting scripted behavior, we will add a new
`inner_map_id` field to json output instead of replacing value.
plain print:
```
$ bpftool map dump id 138
Without Patch:
key:
fc 00 00 00 00 00 00 00 00 00 00 00 00 00 00 05
27 16 06 00
value:
8b 00 00 00
Found 1 element
With Patch:
key:
fc 00 00 00 00 00 00 00 00 00 00 00 00 00 00 05
27 16 06 00
inner_map_id:
139
Found 1 element
```
json print:
```
$ bpftool -p map dump id 567
Without Patch:
[{
"key": ["0xc0","0x00","0x02","0x05","0x27","0x16","0x06","0x00"
],
"value": ["0x38","0x02","0x00","0x00"
]
}
]
With Patch:
[{
"key": ["0xc0","0x00","0x02","0x05","0x27","0x16","0x06","0x00"
],
"value": ["0x38","0x02","0x00","0x00"
],
"inner_map_id": 568
}
]
```
