Compile miniglog into Ceres if enabled on all platforms.

Browse Source 
- Previously if miniglog was being used (on a non-Android system), we
  compiled it into a separate library, against which Ceres then linked.
- This was unsatisfactory as it required miniglog being built as a
  static library when building Ceres as a Windows DLL, because miniglog
  did not use the dllexport/dllimport statements, whilst for other
  platforms when building Ceres as a shared library, miniglog needed to
  be compiled as a shared library.

- We now compile miniglog into Ceres on all platforms, not just on
  Android.
- miniglog now uses the CERES_EXPORT macro to support Windows DLLs.
  This means that miniglog now depends on Ceres' internal/port.h (and
  thus internal/config.h) which define the CERES_EXPORT macro and
  control its behaviour respectively.
- miniglog now also uses localtime_s, not localtime on Windows.
