Revert "Update dependency: handlebars: 3 -> 4"

Because the update broke interpolation of the "patches" variable from the
package definitions (and possibly others), we revert the update for now until we
figured out what is actually wrong here.

This reverts commit 3cb481417b13c5664bb4157d932b8ad4df5cb66d.
