selftests/bpf: check return value of fopen in test_verifier.c
Commit 0a6748740368 ("selftests/bpf: Only run tests if !bpf_disabled")
forgot to check return value of fopen.
This caused some confusion, when running test_verifier (from
tools/testing/selftests/bpf/) on an older kernel (< v4.4) as it will
simply seqfault.
This fix avoids the segfault and prints an error, but allow program to
continue. Given the sysctl was introduced in 1be7f75d1668 ("bpf:
enable non-root eBPF programs"), we know that the running kernel
cannot support unpriv, thus continue with unpriv_disabled = true.
Fixes: 0a6748740368 ("selftests/bpf: Only run tests if !bpf_disabled")
