Jesper Dangaard Brouer deea81228b selftests/bpf: check return value of fopen in test_verifier.c
Commit 0a67487403 ("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 1be7f75d16 ("bpf:
enable non-root eBPF programs"), we know that the running kernel
cannot support unpriv, thus continue with unpriv_disabled = true.

Fixes: 0a67487403 ("selftests/bpf: Only run tests if !bpf_disabled")
