Alexei Starovoitov b429d0b9a7 bpf: Disallow bpf programs call prog_run command. ...

commit 86f44fcec2 upstream.

The verifier cannot perform sufficient validation of bpf_attr->test.ctx_in
pointer, therefore bpf programs should not be allowed to call BPF_PROG_RUN
command from within the program.
To fix this issue split bpf_sys_bpf() bpf helper into normal kern_sys_bpf()
kernel function that can only be used by the kernel light skeleton directly.
