Subject: [PATCH bpf-next v11 5/7] bpf/btf: bump BTF_KFUNC_SET_MAX_CNT

net/bpf/test_run.c is already presenting 20 kfuncs.
net/netfilter/nf_conntrack_bpf.c is also presenting an extra 10 kfuncs.

Given that all the kfuncs are regrouped into one unique set, having
only 2 space left prevent us to add more selftests.

Bump it to 64 for now.
