Fix -Wshadow warning:

    tools/nciattach.c: In function ‘main’:
    tools/nciattach.c:272:9: error: declaration of ‘opt’ shadows a previous local [-Werror=shadow]
      272 |   char *opt;
          |         ^~~
    tools/nciattach.c:236:24: note: shadowed declaration is here
      236 |  int detach, printpid, opt, i, n, ld, err;
          |                        ^~~
