Some Octave packages require OpenGL for their unit tests, e.g.
`octavePackages.image`. Previously, this test script would have
erroneous failures because OpenGL could not be found. [1] suggested
that we add these to the test environment to remove these incorrect
failures.
Fixing OpenGL being missing actually meant that gnuplot needed to be
pulled in, because these unit tests were plotting AND doing graphics.
And because gnuplot needs fonts, we need fontconfig too.

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.
