taskd: fix static linking issue with libuuid/libintl

libuuid depends on libintl in specific scenarios, but since taskd wasn't
using pkg-config to detect libuuid, this dependency on libintl was not
taken into account. This commit adds a patch to taskd that uses
pkg-config to detect libuuid.

Fixes:

+CMakeLists.txt: use pkg-config to detect uuid when possible
+
+In order to take into account the libraries used by libuuid when
+building statically, using pkg-config is recommended. This patch
+therefore improves the CMakeLists.txt to use pkg-config to detect
+libuuid when pkg-config is available.
