selftests/bpf: make sure signal interrupts BPF_PROG_TEST_RUN Simple test that I used to reproduce the issue in the previous commit: Do BPF_PROG_TEST_RUN with max iterations, each program is 4096 simple move instructions. File alarm in 0.1 second and check that bpf_prog_test_run is interrupted (i.e. test doesn't hang). Note: reposting this for bpf-next to avoid linux-next conflict. In this version I test both BPF_PROG_TYPE_SOCKET_FILTER (which uses generic bpf_test_run implementation) and BPF_PROG_TYPE_FLOW_DISSECTOR (which has it own loop with preempt handling in bpf_prog_test_run_flow_dissector).
