gptfdisk: select the libuuid from util-linux if possible. (#2683)

* On x86_gcc2 we only have the libuuid from the libuuid package.
* On all other architectures we can switch to the libuuid from the
  util_linux package.
* The libuuid from util-linux needs libintl, but the latter does
  not have a pkgconfig file, so we need to add "LDFLAGS=-lintl".
