    Add missing header to sccp_utils.c
    
    With newer gcc versions (8.3 tested) compile of sccp_utils.c fails with:
    
        CC       libsccp_la-sccp_utils.lo
      sccp_utils.c: In function 'sccp_utf8_columnwidth':
      sccp_utils.c:1846:2: warning: implicit declaration of function 'setlocale'; did you mean 'ast_setlocale'? [-Wimplicit-function-declaration]
        setlocale(LC_ALL, "");
        ^~~~~~~~~
        ast_setlocale
      sccp_utils.c:1846:12: error: 'LC_ALL' undeclared (first use in this function); did you mean 'AI_ALL'?
        setlocale(LC_ALL, "");
                  ^~~~~~
                  AI_ALL
      sccp_utils.c:1846:12: note: each undeclared identifier is reported only once for each function it appears in
      Makefile:852: recipe for target 'libsccp_la-sccp_utils.lo' failed
      make[7]: *** [libsccp_la-sccp_utils.lo] Error 1
    
    Fix this by adding the missing header.
