efl_mono was assuming ECANCELED as in Linux, which made some tests
fail.
test_simple_futere_cancel and test_cancel_after_resolve checks if
the returned error code is ECANCELED but Eina.Error.ECANCELED was
base on Linux ECANCELED which is diferent from OSX causing:
[ ERROR ] AssertionException: /Users/lucas/expertise/efl1/src/tests/efl_mono/Promises.cs:138 (test_simple_future_cancel) Left hand side "Eina.Error(89)", right hand side "Eina.Error(125)" at Test.AssertEquals[T](T lhs, T rhs, String msg, Int32 line, String file, String member) in /Users/lucas/expertise/efl1/src/tests/efl_mono/TestUtils.cs:line 73 at TestSuite.TestPromises.test_simple_future_cancel() in /Users/lucas/expertise/efl1/src/tests/efl_mono/Promises.cs:line 138 [ FAIL ] TestPromises.test_simple_future_cancel

And iwraper.cs:WrapAssync was only considering Linux ECANCELED thus causing
a rise of an Efl.FutureException: Future failed instead of the expected
TaskCanceledException making fail at TestEoAsyncMethods.test_async_cancel:
[ RUN ] TestEoAsyncMethods.test_async_cancel [ ERROR ] AssertionException: Assertion failed: /Users/lucas/expertise/efl1/src/tests/efl_mono/EoPromises.cs:175 (test_async_cancel) AggregateException must have been TaskCanceledException at Test.Assert(Boolean res, String msg, Int32 line, String file, String member) in /Users/lucas/expertise/efl1/src/tests/efl_mono/TestUtils.cs:line 53 at TestSuite.TestEoAsyncMethods.<>c.<test_async_cancel>b__1_0(Exception x) in /Users/lucas/expertise/efl1/src/tests/efl_mono/EoPromises.cs:line 175 at System.AggregateException.Handle(Func`2 predicate) at TestSuite.TestEoAsyncMethods.test_async_cancel() in /Users/lucas/expertise/efl1/src/tests/efl_mono/EoPromises.cs:line 171 [ FAIL ] TestEoAsyncMethods.test_async_cancel
