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.
