treewide: Replace transfig with fig2dev

Reasons:

- transfig never get upstream update since it was added to nixpkgs 2006,
  according to [fig2dev Debian changelog][1], upstream maintainership
  was taken over at 2016, and renamed to fig2dev.

- [Debian][2], [ArchLinux][3], [HomeBrew][4] all use fig2dev to replace
  transfig.

- transfig builds [failed][5] on aarch64-darwin, fig2dev builds fine.

- One less package to maintain.
