The properties added by commit 4a62e3d9 (macOS: Add
OSX_COMPATIBILITY_VERSION and OSX_CURRENT_VERSION properties,
2020-01-24, v3.17.0-rc1~80^2~1) are general-purpose for all platforms
using Mach-O formats and not just on OS X.  Rename them accordingly.
The properties are new to the CMake 3.17 release so we can rename
them without compatibility concerns.

Fixes: #20442
