bpf: save extended inner map info for percpu array maps as well

Browse source

ARRAY_OF_MAPS and HASH_OF_MAPS map types have special logic to save
a few extra fields required for correct operations of ARRAY maps, when
they are used as inner maps. PERCPU_ARRAY maps have similar
requirements as they now support generating inline element lookup
logic. So make sure that both classes of maps are handled correctly.
