[test] Prepare tests to run on Android

- Expand operating system checks such that Glibc is properly
  imported on Android.
- For tests that are unsupported on platforms that normally
  do not support an Objective-C runtime, expand the unsupported
  checks to include Android.
- Pass the `-sdk` parameter when invoking `%target-sil-opt`.
- Expect failures when testing semaphores, which are not included
  in Android Bionic.
