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

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=19448f40a0e9cfd6b3ff7f22c38a4b893cf36690
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
