uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+ <para>
+  Matomo is a real-time web analytics application. This module configures
+  php-fpm as backend for Matomo, optionally configuring an nginx vhost as well.
+ </para>
+ <para>
+  An automatic setup is not suported by Matomo, so you need to configure Matomo
+  itself in the browser-based Matomo setup.

+ <section xml:id="module-services-matomo-database-setup">
+  <title>Database Setup</title>
+
+  <para>
+   You also need to configure a MariaDB or MySQL database and -user for Matomo
+   yourself, and enter those credentials in your browser. You can use
+   passwordless database authentication via the UNIX_SOCKET authentication
+   plugin with the following SQL commands:
+<programlisting>
+# For MariaDB
+INSTALL PLUGIN unix_socket SONAME 'auth_socket';
+CREATE DATABASE matomo;
+CREATE USER 'matomo'@'localhost' IDENTIFIED WITH unix_socket;
+GRANT ALL PRIVILEGES ON matomo.* TO 'matomo'@'localhost';
+
+# For MySQL
+INSTALL PLUGIN auth_socket SONAME 'auth_socket.so';
+CREATE DATABASE matomo;
+CREATE USER 'matomo'@'localhost' IDENTIFIED WITH auth_socket;
+GRANT ALL PRIVILEGES ON matomo.* TO 'matomo'@'localhost';
+</programlisting>
+   Then fill in <literal>matomo</literal> as database user and database name,
+   and leave the password field blank. This authentication works by allowing
+   only the <literal>matomo</literal> unix user to authenticate as the
+   <literal>matomo</literal> database user (without needing a password), but no
+   other users. For more information on passwordless login, see
+   <link xlink:href="https://mariadb.com/kb/en/mariadb/unix_socket-authentication-plugin/" />.
+  </para>
+
+  <para>
+   Of course, you can use password based authentication as well, e.g. when the
+   database is not on the same host.

+     Matomo will warn you that the JavaScript tracker is not writable. This is
+     because it's located in the read-only nix store. You can safely ignore
+     this, unless you need a plugin that needs JavaScript tracker access.
