kanshi: add dependency on libvarlink to enable building kanshictl
<!-- Uncomment relevant sections and delete options which are not applicable -->

The most recent release of kanshi added an optional kanshictl utility, which
uses varlink. If libvarlink-devel is available at build time, meson will
automatically enable that functionality and provide both the binary and the man
page for it.
