guide: copy fonts from dist/static/

The fonts used by the guide are also the ones use by cockpit itself:
instead of copying them out of the node_modules/ directory, copy them
from dist/static/.  This allows us to perform the copy from somewhere
which is shipped with the tarball vs. somewhere that's not and means
that we can drop the second copy of these files that's disted along with
the guide.
