libtool: rework revision to fix OS X breakage
It seems the OS X linker restricts the revision field to 8 bits.
Rework how we calculate that value and pack it in closer to fit.
It might produce some collisions if we get to like 2.2.8, but oh
well ... this field doesn't need to be super exact.
Fixes #214.
