import: Remove Nix importer. 

This importer has suffered from bitrot and no longer works with current
Nix and Nixpkgs.  See <https://bugs.gnu.org/32339> and
<https://bugs.gnu.org/36255>.

* guix/import/snix.scm, guix/scripts/import/nix.scm,
tests/snix.scm: Remove.
* Makefile.am (MODULES, SCM_TESTS): Remove them.
* guix/scripts/import.scm (importers): Remove "nix".
* build-aux/test-env.in: Remove NIXPKGS variable.
* configure.ac: Remove '--with-nixpkgs' option.
* doc/guix.texi (Invoking guix import): Remove bit about "guix import
nix".
* etc/completion/fish/guix.fish: Likewise.

guix import json hello.json
@end example
@item nix
Import metadata from a local copy of the source of the
@uref{https://nixos.org/nixpkgs/, Nixpkgs distribution}@footnote{This
relies on the @command{nix-instantiate} command of
@uref{https://nixos.org/nix/, Nix}.}. Package definitions in Nixpkgs are
typically written in a mixture of Nix-language and Bash code. This
command only imports the high-level package structure that is written in
the Nix language. It normally includes all the basic fields of a
package definition.
When importing a GNU package, the synopsis and descriptions are replaced
by their canonical upstream variant.
Usually, you will first need to do:
@example
export NIX_REMOTE=daemon
@end example
@noindent
so that @command{nix-instantiate} does not try to open the Nix database.
As an example, the command below imports the package definition of
LibreOffice (more precisely, it imports the definition of the package
bound to the @code{libreoffice} top-level attribute):
@example
guix import nix ~/path/to/nixpkgs libreoffice
@end example
@item hackage
@cindex hackage
