Using outputsToInstall the intended behaviour of including host and dnsutils
when bind is installed can be implemented instead of using symlinks to fix
installing all outputs individually with nix-env.
Fixes#19761.
The list of permitted syscalls in the seccomp sandbox is only defined
for x86. It fails to build otherwise:

These tools are commonly used but don't require the other bind binaries.
Bind's libs are used, so they've also been split into an extra output.
The old version of host isn't maintained anymore and was removed From Debian
back in 2009: https://packages.qa.debian.org/h/host.html

(My OCD kicked in today...)
Remove repeated package names, capitalize first word, remove trailing
periods and move overlong descriptions to longDescription.
I also simplified some descriptions as well, when they were particularly
long or technical, often based on Arch Linux' package descriptions.
I've tried to stay away from generated expressions (and I think I
succeeded).
Some specifics worth mentioning:
* cron, has "Vixie Cron" in its description. The "Vixie" part is not
mentioned anywhere else. I kept it in a parenthesis at the end of the
description.
* ctags description started with "Exuberant Ctags ...", and the
"exuberant" part is not mentioned elsewhere. Kept it in a parenthesis
at the end of description.
* nix has the description "The Nix Deployment System". Since that
doesn't really say much what it is/does (especially after removing
the package name!), I changed that to "Powerful package manager that
makes package management reliable and reproducible" (borrowed from
nixos.org).
* Tons of "GNU Foo, Foo is a [the important bits]" descriptions
is changed to just [the important bits]. If the package name doesn't
contain GNU I don't think it's needed to say it in the description
either.
The BIND configure script finds extra dependencies in /usr/include and /usr/lib,
and activates additional features if it does. This may cause the build to fail
on systems that cannot use a chroot environment. Actively disabling those
additional features prevents this issue from occurring.
