[roll] Roll fuchsia [tee] Stub TEE_UnmaskCancellation

Instead of panicking, return true from TEE_UnmaskCancellation. This is
needed to pass preconditions for some tests, even though the tests
themselves do not rely on this functionality. Proper implementation of
Cancellation APIs is left as a TODO.

As a result of this change, regression1038 no longer panics and fails.
It talks to the TA successfully and determines to skip the test because
it doesn't support MTE.
