[Buildroot] [PATCH] c-ares: define random file

[gustavo.zacarias at free-electrons.com]

From: Gustavo Zacarias <gustavo.zacarias at free-electrons.com>

When cross-compiling it assumes there's none, however that's not true.
Specify the usual /dev/urandom for this usage, it's used for random key
generation on startup.
