Subject: selftests/bpf: Use BTF-defined key/value for map definitions
Patch-mainline: v5.16-rc1
Git-commit: bd368cb554d685c60e65ab799bf238663c682105
References: jsc#PED-1377

Change map definitions in BPF selftests to use BTF-defined
key/value types. This unifies the map definitions and ensures
libbpf won't emit warning about retrying map creation.
