Added Tenacity version in CMakeLists.txt

Doesn't change anything functionality-wise for now, particularly because of
my hesitation with this change as far as hard-coding the version again as a
fallback is concerned.

Audacity's version variable was also reverted in contrast to
56c953a14d for compatibility reasons with older
project files or for project file compatibility with newer versions of
Audacity.
