libbpf: ringbuf: Allow to consume up to a certain amount of items
In some cases, instead of always consuming all items from ring buffers
in a greedy way, we may want to consume up to a certain amount of items,
for example when we need to copy items from the BPF ring buffer to a
limited user buffer.
This change allows to set an upper limit to the amount of items consumed
from one or more ring buffers.
