Only #define SCUMMVM_SVN_REVISION for base/version.cpp (at most), to

Also add a safeguard to prevent code from accidentally using the
internal header file base/internal_version.h.

* Added a yes/no variable _unix to configure, which controls when
-DUNIX is added to DEFINES
* Enable SEQ MIDI via _seq_midi by default on UNIX type systems,
except for those which override that.
* Switch SEQ MIDI code to check #define USE_SEQ_MIDI
(alternatively, we could compile it only conditionally...)
