Subject: [PATCH] emacsPackages.dap-mode: fix build

https://hydra.nix-community.org/build/2991612
(cherry picked from commit fe5312cd441714a518c3585297ba0f1915e899b8)

This was originally committed to the staging-next branch.  To make it
reach users sooner, we revert it on the staging-next branch and
reapply it to the master branch.

Closes: https://github.com/nix-community/emacs-overlay/issues/467
