Implement library versioning for macOS
Currently, the Makefile provides no version information about library to
the macOS linker. This makes the linker fill in zeroes for
`compatibility_version` and `current_version` by default.
This is a problem for when you make breaking changes to the library that
require re-compilation of linked software. The new library will still
have a `compatibility_version` of `0.0.0`, which misleads the linker
into believing the new library is a drop-in replacement for the old one.
Let's fix that by making sure we pass version information correctly to
the linker on macOS.
NOTE: Since this increments the `compatibility_version` of the DSO from
`0.0.0` to `1.0.0`, this change will require re-compilation of any macOS
software that dynamically link against `libkeccak`. If you'd like to
avoid this inconvenience for your users, you may wish to wait until you
decide to increment `LIB_MAJOR` or otherwise make breaking changes to
`libkeccak` before merging this change.
