Subject: [PATCH bpf-next 1/2] selftests/bpf: add static to enable_all_controllers()

Add static to enable_all_controllers() to get rid from annoying warn:

samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:44:5:
warning: no previous prototype for ‘enable_all_controllers’
[-Wmissing-prototypes]
 int enable_all_controllers(char *cgroup_path)

while samples/bpf build.
