Andrey Ignatov 06ac0186bd selftests/bpf: Test BPF_F_REPLACE in cgroup_attach_multi 
Test replacing a cgroup-bpf program attached with BPF_F_ALLOW_MULTI and
possible failure modes: invalid combination of flags, invalid
replace_bpf_fd, replacing a non-attachd to specified cgroup program.

Example of program replacing:

  # gdb -q --args ./test_progs --name=cgroup_attach_multi
  ...
  Breakpoint 1, test_cgroup_attach_multi () at cgroup_attach_multi.c:227
  (gdb)
  [1]+  Stopped                 gdb -q --args ./test_progs --name=cgroup_attach_multi
  # bpftool c s /mnt/cgroup2/cgroup-test-work-dir/cg1
  ID       AttachType      AttachFlags     Name
  2133     egress          multi
  2134     egress          multi
  # fg
  gdb -q --args ./test_progs --name=cgroup_attach_multi
  (gdb) c
  Continuing.

  Breakpoint 2, test_cgroup_attach_multi () at cgroup_attach_multi.c:233
  (gdb)
  [1]+  Stopped                 gdb -q --args ./test_progs --name=cgroup_attach_multi

  ID       AttachType      AttachFlags     Name
  2139     egress          multi
  2134     egress          multi
