This works around a build problem that occurs because NUnit ships with a
P/Invoke to a function that doesn't exist on Apple platforms:
MTOUCH : error MT5210: Native linking failed, undefined symbol: _GetVersionEx. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in. [/Users/xamarinqa/myagent/_work/8/s/xamarin-macios/tests/xharness/tmp-test-dir/monotouch-test58/monotouch-test-tvos.csproj]
MTOUCH : error MT5201: Native linking failed. Please review the build log and the user flags provided to gcc: -fembed-bitcode-marker [/Users/xamarinqa/myagent/_work/8/s/xamarin-macios/tests/xharness/tmp-test-dir/monotouch-test58/monotouch-test-tvos.csproj]
clang : error : linker command failed with exit code 1 (use -v to see invocation) [/Users/xamarinqa/myagent/_work/8/s/xamarin-macios/tests/xharness/tmp-test-dir/monotouch-test58/monotouch-test-tvos.csproj]
Also fix an issue in mtouch where we would overwrite any previous --dlsym
values; they're now accumulative (`--dlsym:foo.dll --dlsym:bar.dll` works
as expected)

* Touch.Client references the official NUnitLite package, which means we're using
a non-forked version of NUnit.
* This makes it easier for our .NET 5 effort, since we won't have to port an ancient
version of NUnitLite to .NET 5 (nor will we have to keep using it in our existing
code, we can use more modern NUnit patterns).
* Reference MonoTouch.Dialog from the NuGet package. This also eases the .NET 5 effort,
since we won't have to port MonoTouch.Dialog to .NET 5 (we'll probably still do it
though at some point, but it doesn't have to be done right away), nor build it
ourselves / ship it.
