perf build: Fix btf__load_from_kernel_by_id() feature check

The btf__load_from_kernel_by_id() only takes one arg, not two.

Committer notes:

I tested it just with an older libbpf, one where
btf__load_from_kernel_by_id() wasn't introduced yet.

A test with a newer dynamic libbpf would fail because the
btf__load_from_kernel_by_id() is there, but takes just one arg.
