gettext 1.0 changed msginit to merge into existing output files
instead of overwriting them. When po4a passes an empty PO file as the
output target, this produces a PO with stripped headers and corrupted
UTF-8 content (e.g. "nämes" becomes "nmes").
Fix by removing empty output files before calling msginit, so it
creates a fresh PO file with proper headers.

Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
The motivation behind this is wanting to reduce the reverse closure size of
texlive.
When internationalizing tex files, Po4a attempts to follow included files. In
order to find the correct files, po4a uses texlive's file-finding utility
kpsewhich. This commit replaces texlive with a tiny shell script, which is
precisely good enough to run the tests.
This does not change the resulting package in any way, it only affects how the
test is run.
Fixes#71296 (Po4a build get stuck in a loop)
Term::ReadKey is an optional dependency. From upstream:
> This module is used to retrieve the terminal's line width.
> If it is not present, the line width can be specified with the COLUMN environment variable.
