backports: Add empty implementation for skb_get_kcov_handle()
In kernel >= 5.11 skb_get_kcov_handle() returns skb->kcov_handle when
CONFIG_KCOV is set and otherwise 0. It should even be fine when
CONFIG_KCOV is set on older kernels to return 0 here, kcov will not work
as good as on recent kernels, but it should work ok.
