chore(3p/nix): unvendor tvix 0.1 r/4098

Nothing is using this now, and we'll likely never pick this up again,
but we learned a lot in the process.

Every now and then this breaks in some bizarre way on channel bumps
and it's just a waste of time to maintain that.

-
-
-<varlistentry><term><option>--keep-failed</option> / <option>-K</option></term>
-
-  <listitem><para>Specifies that in case of a build failure, the

-  the build takes place should not be deleted.  The path of the build
-  directory is printed as an informational message.

-
-
-<varlistentry><term><option>--fallback</option></term>
-
-  <listitem>
-
-  <para>Whenever Nix attempts to build a derivation for which
-  substitutes are known for each output path, but realising the output
-  paths through the substitutes fails, fall back on building the
-  derivation.</para>
-
-  <para>The most common scenario in which this is useful is when we
-  have registered substitutes in order to perform binary distribution
-  from, say, a network repository.  If the repository is down, the
-  realisation of the derivation will fail.  When this option is
-  specified, Nix will build the derivation instead.  Thus,
-  installation from binaries falls back on installation from source.
-  This option is not the default since it is generally not desirable
-  for a transient failure in obtaining the substitutes to lead to a
-  full build from source (with the related consumption of
-  resources).</para>

-
-</varlistentry>
-
-<varlistentry><term><option>--no-build-hook</option></term>
-
-  <listitem>
-
-  <para>Disables the build hook mechanism.  This allows to ignore remote
-  builders if they are setup on the machine.</para>
-
-  <para>It's useful in cases where the bandwidth between the client and the
-  remote builder is too low.  In that case it can take more time to upload the
-  sources to the remote builder and fetch back the result than to do the
-  computation locally.</para>

-
-
-
-<varlistentry><term><option>--readonly-mode</option></term>
-
-  <listitem><para>When this option is used, no attempt is made to open
-  the Nix database.  Most Nix operations do need database access, so
-  those operations will fail.</para></listitem>

-
-<varlistentry><term><option>--arg</option> <replaceable>name</replaceable> <replaceable>value</replaceable></term>
-
-  <listitem><para>This option is accepted by
-  <command>nix-env</command>, <command>nix-instantiate</command> and
-  <command>nix-build</command>.  When evaluating Nix expressions, the
-  expression evaluator will automatically try to call functions that
-  it encounters.  It can automatically call functions for which every
-  argument has a <link linkend='ss-functions'>default value</link>
-  (e.g., <literal>{ <replaceable>argName</replaceable> ?
-  <replaceable>defaultValue</replaceable> }:
-  <replaceable>...</replaceable></literal>).  With
-  <option>--arg</option>, you can also call functions that have
-  arguments without a default value (or override a default value).
-  That is, if the evaluator encounters a function with an argument
-  named <replaceable>name</replaceable>, it will call it with value
-  <replaceable>value</replaceable>.</para>
-
-  <para>For instance, the top-level <literal>default.nix</literal> in
-  Nixpkgs is actually a function:
-
-<programlisting>
-{ # The system (e.g., `i686-linux') for which to build the packages.
-  system ? builtins.currentSystem
-  <replaceable>...</replaceable>
-}: <replaceable>...</replaceable></programlisting>
-
-  So if you call this Nix expression (e.g., when you do
-  <literal>nix-env -i <replaceable>pkgname</replaceable></literal>),
-  the function will be called automatically using the value <link
-  linkend='builtin-currentSystem'><literal>builtins.currentSystem</literal></link>
-  for the <literal>system</literal> argument.  You can override this
-  using <option>--arg</option>, e.g., <literal>nix-env -i
-  <replaceable>pkgname</replaceable> --arg system
-  \"i686-freebsd\"</literal>.  (Note that since the argument is a Nix
-  string literal, you have to escape the quotes.)</para></listitem>

-</varlistentry>
-
-
-<varlistentry><term><option>--argstr</option> <replaceable>name</replaceable> <replaceable>value</replaceable></term>
-
-  <listitem><para>This option is like <option>--arg</option>, only the
-  value is not a Nix expression but a string.  So instead of
-  <literal>--arg system \"i686-linux\"</literal> (the outer quotes are
-  to keep the shell happy) you can say <literal>--argstr system
-  i686-linux</literal>.</para></listitem>

-  expression being evaluated.  (<command>nix-env</command>,
-  <command>nix-instantiate</command>, <command>nix-build</command> and
-  <command>nix-shell</command> only.)  The <emphasis>attribute
-  path</emphasis> <replaceable>attrPath</replaceable> is a sequence of
-  attribute names separated by dots.  For instance, given a top-level
-  Nix expression <replaceable>e</replaceable>, the attribute path
-  <literal>xorg.xorgserver</literal> would cause the expression
-  <literal><replaceable>e</replaceable>.xorg.xorgserver</literal> to
-  be used.  See <link
-  linkend='refsec-nix-env-install-examples'><command>nix-env
-  --install</command></link> for some concrete examples.</para>
-
-  <para>In addition to attribute names, you can also specify array
-  indices.  For instance, the attribute path
-  <literal>foo.3.bar</literal> selects the <literal>bar</literal>

-  <literal>foo</literal> attribute of the top-level
