Updated to version 2.012.

Pkgsrc changes:
  - Requires p5-IO-Compress-Base-2.012 and p5-Compress-Raw-Zlib-2.012

It looks like there were no functional changes (see the Changes file) and
the version number increased only to stay in line with all the other Zlib
modules. Anyway, Compress::Zlib 2.012 demands version 2.012 of IO::Compress::*, \ 
thus this update.
