workstation: Switch to Nix-managed Firefox

I had this laying around locally for a year now and I'm still not really
happy with some things, for example not having yet full source builds of
the extensions and a few config options not yet managed by Nix (eg.
search engines).

However, since Firefox takes a while to build it's a bit tedious to
always do it directly (and locally) after I update my machines. Having
this part of my workstation profile should make sure that my version of
Firefox is available at all times.
