cmd/exception: missing include string.h

When building qemu_arm64_defconfig with CMD_EXCEPTION a build error occurs:

    In file included from cmd/arm/exception64.c:87:
    include/exception.h: In function ‘exception_complete’:
    include/exception.h:41:23: error: implicit declaration of
    function ‘strlen’ [-Wimplicit-function-declaration]
       41 |                 len = strlen(argv[1]);
          |                       ^~~~~~

Add the missing include.
