Fix the Android unit tests.

- One of the unit test binaries refused to link due to
  missing linker flags.

- The WriteDSODebug() function now works on Android, so
  do not special-case it anymore.

- Ensure android/run-checks.sh will complain properly if
  the client unit test suite fails on Android. It used to
  consider that such failures were acceptable. Note that
  it still considers failures when running the tools and
  processor test suite on the device normal (fixing this
  is a lot harder, and these parts of Breakpad typically
  never run on a device, but on the host).
