cdc,index: replace boost::ends_with() with .ends_with()

since C++20, std::string and std::string_view started providing
`ends_with()` member function, the same applies to `seastar::sstring`,
so there is no need to use `boost::ends_with()` anymore.

in this change, we switch from `boost::ends_with()` to the member
functions variant to

- improve the readability
- reduce the header dependency
