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

This is a followup to 2e3e5d21988fc2cafb2a9eaf4b00976ea425629d.

Reported by Mark H Weaver <mhw@netris.org>.
* build-aux/test-env.in: Add 'guile' invocation before 'guix download'
invocation to make sure 'guix-daemon' is listening.
Fixes a regression introduced in
a9edb211e733b8b34e67ec3b4450567e9376986f where the .log files of the .sh
tests would not contain stderr.
* build-aux/test-env.in: Redirect stderr only when --quiet-stderr is
passed.
* Makefile.am (SCM_LOG_DRIVER): Add --quiet-stderr.
* pre-inst-env.in: Move to ...
* build-aux/pre-inst-env.in: ... here.
* test-env.in: Move to ...
* build-aux/test-env.in: ... here.
* configure.ac (AC_CONFIG_FILES): Adapt to this. Keep the generated
scripts in their current location which is $(top_builddir).
