Add -C for copying files

Some files prefer to be copies instead of symlinks---for example,
OpenSSH ignores symlinks. Add the `-C` option to mkrc(1) and rcup(1) to
handle this.

    mkrc -C .ssh
    rcup -C ssh

This does raise a synchronization problem that I do not yet know how to
solve; namely, what to do when the rc file changes. Perhaps a `rcsync`
command is in order; perhaps `rcup` should handle this; perhaps `rcsync`
is a better name for `rcup`.
