Subject: [PATCH] libtac/lib/magic.c: fix build on uclibc

Commit 7e990f9db6d8805d369876f45964df87efad9e08 replaced _GNU_SOURCE by
AC_SYSTEM_EXTENSIONS. This is fine but then config.h must be included
before system includes otherwise build fails with uclibc on:

libtac/lib/magic.c: In function 'magic':
libtac/lib/magic.c:70:11: error: implicit declaration of function 'getrandom' [-Werror=implicit-function-declaration]
     ret = getrandom(&num, sizeof(num), GRND_NONBLOCK);
           ^

Fixes:
