bpf: fix BTF limits
[ Upstream commit a0791f0df7d212c245761538b17a9ea93607b667 ]
vmlinux BTF has more than 64k types.
Its string section is also at the offset larger than 64k.
Adjust both limits to make in-kernel BTF verifier successfully parse in-kernel BTF.
Fixes: 69b693f0aefa ("bpf: btf: Introduce BPF Type Format (BTF)")
