Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3c7e58590600eca3402f08e7fbdf4f2d1e36c5c8

-------------------------------------------------

As part of the effort to move towards a v1.0 for libbpf, rename
btf__load() function, used to "upload" BTF information into the kernel,
as btf__load_into_kernel(). This new name better reflects what the
function does.
