tools: Fix strncat() usage in hciconfig/hcitool According to strncat() manpage: "If src contains n or more characters, strncat() writes n+1 characters to dest (n from src plus the terminating null byte). Therefore, the size of dest must be at least strlen(dest)+n+1" While the current usage of strncat() cannot cause an overflow, if a bigger string is added to the switch()'s without increasing the static buffer, it would overflow by one byte due to the incorrect size calculation. Fixes clang errors like: tools/hciconfig.c:827:33: error: the value of the size argument in 'strncat' is too large, might lead to a buffer overflow [-Werror,-Wstrncat-size]
