selftests/bpf: Declare bpf_log_buf variables as static

The cgroup selftests did not declare the bpf_log_buf variable as static, leading
to a linker error with GCC 10 (which defaults to -fno-common). Fix this by
adding the missing static declarations.

Fixes: 257c88559f ("selftests/bpf: Convert test_cgroup_attach to prog_tests")
