Use the bundled fontconfig for ui/gfx_unittests

The target gfx_unittests used the system's fontconfig which
stopped working on Ubuntu 16.04 without sysroot when the tests
started using FcConfigParseAndLoadFromMemory which is a
newly (2017) added fontconfig function.

The test should have used third_party/fontconfig all the time
but the test didn't have the necessary deps in the build system
for that to happen.
