gnu: Move guile-charting to (gnu packages plotutils).

This removes the dependency from (gnu packages guile)
to (gnu packages gtk), which potentially reduces the memory/IO/CPU
footprint given that 'guile' is used during bootstrap.

* gnu/packages/guile.scm (guile-charting): Move to...
* gnu/packages/plotutils.scm (guile-charting): ... here.
