    tests/tcg/meson.build: fix build_test_depends

    build_test_depends is supposed to be an array, not a custom target. In
    case we go through this path, we have an error with following lines:

          exe_depends = build_test_depends
          if 'depends' in setup
            exe_depends += setup['depends']
          endif

    where meson complains that custom target has no += operator.
