fs: for boost 1.74 and up, use c++17 compatible copy_options

Browse Source 
In boost 1.74.0, boost::filesystem adapted path::copy_option enum
to be the same as the enum in the fs::path from c++17, which is
now called copy_options, and its member "overwrite_if_exists"
is now called "overwrite_existing". In boost 1.85, the deprecated
copy_option enum is fully removed.

Because Dogecoin Core currently supports boost 1.60 and up,
conditionally implement the new enum based on the boost version
that is built against.
