devel/arcanist: Split into arcanist-lib and arcanist.
The arcanist port has always conflicted with archivers/arc, but if the port is installed without the symlink in PREFIX/bin, there is no issue. A user expecting to be able to use arcanist in this way can alias arcanist in their .cshrc or similar and only install the -lib port.
