[Buildroot] [PATCH] gnutls: use included unistring unless libunistring is selected

[Sven Neumann]

Use the included copy of libunistring unless BR2_PACKAGE_LIBUNISTRING
is already selected.

The resulting gnutls library with libunistring included is about 1.2 MB
smaller than the sum of libgnutls and libunistring.
