treewide: substitute finalAttrs.pname for strings

[pbsds]

Based on #410679, this time targeting finalAttrs.pname. Limited to pkgs/by-name, part of #346453
I widened the grep to allow for more patterns where finalAttrs.pname are used.

Should be zero rebuilds.

All candidates were made using:

#!/usr/bin/env nix-shell
#!nix-shell -I nixpkgs=. --pure -i bash -p ripgrep sd jq git git-wait lix util-linux

# not suprises plz
export NIX_PATH= # no nixpkgs-overlays
export NIXPKGS_CONFIG=

export NIXPKGS_ALLOW_UNFREE=1
export NIXPKGS_ALLOW_INSECURE=1
export NIXPKGS_ALLOW_BROKEN=1

git-wait restore .

diff packages{,2}.json is empty, indicating that no package nor src derivation has changed, nor have I introduced any eval failures.
I checked and cherry-picked the changes using GIT_DIFF_OPTS='-u20' git -c interactive.singleKey=true add --patch along to some music. I then tested merging against master, staging and staging-next
