Subject: selftests/bpf: Don't check for btf fd in test_btf
Patch-mainline: v5.6-rc1
Git-commit: 396b83fa75a3deb9aa68296c090f4eb540917d9d
References: bsc#1177028

After commit 0d13bfce023a ("libbpf: Don't require root for
bpf_object__open()") we no longer load BTF during bpf_object__open(),
so let's remove the expectation from test_btf that the fd is not -1.
The test currently fails.

Before:
BTF libbpf test[1] (test_btf_haskv.o): do_test_file:4152:FAIL bpf_object__btf_fd: -1
BTF libbpf test[2] (test_btf_newkv.o): do_test_file:4152:FAIL bpf_object__btf_fd: -1
BTF libbpf test[3] (test_btf_nokv.o): do_test_file:4152:FAIL bpf_object__btf_fd: -1

After:
BTF libbpf test[1] (test_btf_haskv.o): OK
BTF libbpf test[2] (test_btf_newkv.o): OK
BTF libbpf test[3] (test_btf_nokv.o): OK

Fixes: 0d13bfce023a ("libbpf: Don't require root for bpf_object__open()")
