Anton Protopopov 44481e4925 bpf: generalize and export map_get_next_key for arrays ...

The kernel/bpf/array.c file defines the array_map_get_next_key()
function which finds the next key for array maps. It actually doesn't
use any map fields besides the generic max_entries field. Generalize
it, and export as bpf_array_get_next_key() such that it can be
re-used by other array-like maps.
