fix(libxrpl): change library names in Conan recipe (#4831)

Use consistent platform-agnostic library names on all platforms.

Fix an issue that prevents dependents like validator-keys-tool from
linking to libxrpl on Windows.

It is bad practice to change the binary base name depending on the
platform. CMake already manipulates the base name into a final name that
fits the conventions of the platform. Linkers accept base names on the
command line and then look for conventional names on disk.
