[PATCH v2] mem: fix displaying heap ID failed for heap info command

[Huisong Li]

The telemetry lib has added a allowed characters set for dictionary names.
Please see commit 2537fb0c5f34 ("telemetry: limit characters allowed in
dictionary names")

The space is not in this set, which cause the heap ID in /eal/heap_info
cannot be displayed. Additionally, 'heap' is also misspelling. So use
'Heap_id' to replace 'Head id'.

Fixes: e6732d0d6e26 ("mem: add telemetry infos")
Fixes: 2537fb0c5f34 ("telemetry: limit characters allowed in dictionary names")
