The upstream library rclone uses for rclone mount no longer supports freebsd. Not only is it broken, but it no longer compiles. This patch disables rclone mount for freebsd. However all is not lost for freebsd users - compiling rclone with the `cmount` tag, so `go install -tags cmount` will install a working `rclone mount` command which uses cgofuse and the libfuse C library directly. Note that the binaries from rclone.org will not have mount support as we don't have a freebsd build machine in CI and it is very hard to cross compile cmount.
