Fix dylib versioning in pip packages for macOS

Browse source 
Adds proper -compatibility_version and -current_version linker flags
for macOS builds using the mk_util.py build system.

This resolves issue #6651 where .dylib files in pip packages had
incorrect version info (0.0.0) compared to homebrew builds which
had proper versioning.

The fix adds the appropriate linker flags to SLIBEXTRAFLAGS when
building on macOS:
- compatibility_version: major.minor.0 (minimum compatible version)
- current_version: major.minor.build (current library version)

This ensures pip package dylibs will have correct version metadata
that matches the actual Z3 version, fixing linking issues for
users who depend on proper dylib versioning.

Fixes #6651
