zlibWrapper: Update for zlib 1.2.12 (#3217)
In zlib 1.2.12 the OF macro was changed to _Z_OF breaking any
project that used zlibWrapper. To fix this the OF has been
changed to _Z_OF everywhere and _Z_OF is defined as OF in the
case it is not yet defined for zlib 1.2.11 and older.

Fixes: https://github.com/facebook/zstd/issues/3216
