libbpf: Skip bpf_object__probe_loading() when BPF token is in use

bpf_object__probe_loading() tries to load trivial SOCKET_FILTER and
TRACEPOINT programs to verify the BPF environment works.  When a
BPF token is in use with restricted program type permissions, these
probe loads may fail because the token does not allow the specific
program types, even though BPF loading is perfectly functional.

Fix by skipping the probe when a token FD is present: BPF token
creation itself proves the kernel has a working BPF subsystem.
Real BPF issues will be caught during actual program and map loading.
