[LTP] [PATCH 1/2] tst_cgroup: Fix -Wstringop-truncation warning

[Petr Vorel]

Add space for null terminator to fix warning:

tst_cgroup.c:505:17: warning: ‘__builtin_strncpy’ output may be truncated copying 255 bytes from a string of length 255 [-Wstringop-truncation]
  505 |                 strncpy(cgroup_test_dir, test_dir_name, NAME_MAX);
      |                 ^

Fixes: ebebdd735 ("API/cgroup: Implement tst_cg_load_config")
