string-list: use bool instead of int for "exact_match"

The "exact_match" parameter in "get_entry_index" is used to indicate
whether a string is found or not, which is fundamentally a true/false
value. As we allow the use of bool, let's use bool instead of int to
make the function more semantically clear.
