xprintidle-ng: fix build

    sha256 = "0a5024vimpfrpj6w60j1ad8qvjkrmxiy8w1yijxfwk917ag9rkpq";

  };

  patches = [

    ./fix-config_h-includes-should-be-first.patch

  ];

  postPatch = ''

    substituteInPlace configure.ac \

      --replace "AC_PREREQ([2.62])" "AC_PREREQ([2.64])"

Fixes the config.h include error during build:

```console

In file included from src/xprintidle-ng.c:36:

lib/time.h:28:3: error: #error "Please include config.h first."

    28 |  #error "Please include config.h first."

      |   ^~~~~

```

Introduced since gnulib upgrade:

* https://github.com/coreutils/gnulib/commit/8ad7bc6

* https://lists.gnu.org/archive/html/bug-gnulib/2023-04/msg00088.html

* https://www.gnu.org/software/gnulib/manual/html_node/Source-changes.html

The last version of gnulib now checks that config.h is the first include

in every compilation unit.

This is not the case with the xprintidle-ng source code, so this patch

moves these `config.h` inclusions to be first.
