remove contrib/scalar to avoid cruft in git-core-doc

The scalar command is being worked on incrementally upstream.

As it matures, we may consider building and distributing it.  Whether
that will happen before it graduates from contrib or not is anyone's
guess.

For the moment, remove it to avoid cruft in git-core-doc.
