Compiler is not happy about the recently added code:

lib/sys_info.c:52:19: error: variable 'sys_info_avail' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
   52 | static const char sys_info_avail[] = "tasks,mem,timers,locks,ftrace,all_bt,blocked_tasks";
      |                   ^~~~~~~~~~~~~~

Fix it in the same way how, for example, lib/vsprintf.c does in the similar
cases, i.e. by using string literal directly as sizeof() parameter.
