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.

This PR is part of the networking.* namespace cleanup.
ssmtp used to be configured via `networking.defaultMailServer` which is
sort of misleading since it provides options only for ssmtp. Other
dumb mail relays like nullmailer have always been living under
services.
The intent of this PR is to align ssmtp's options with those of similar
services. Specifically, two renames have been done:
* Rename `networking.defaultMailHost` to `services.ssmtp`.
* Rename `directDelivery` to `enable` because this is what it basically does.
